Delayed into 2023?  Not listed before CFT.

ATLAS V & VULCAN

Upcoming Atlas V launches include the first crewed flight of Boeing's Starliner spacecraft to the space station in February TBD. Vulcan will use the same launch pad when it flies. [October 8 update]
The USSF-51 is officially described as a classified payload, like the two satellites that will be launched aboard the last two Delta IV Heavy launches. The Atlas V will also launch the NROL-107 satellite from SLC-41, but this launch is not listed before the Starliner CFT either.

and your point is?
The Launch Viewing Guide website doesn't mention the USSF-51, which is why someone speculated that USSF-51 may be delayed to next year.

Your reply, Vahe, didn't answer my question.  As a reply, it was off-topic.

Your reply could instead have been a no-new-information-provided post in this thread.

If no one currently has an answer to my launch scheduling question, then let's move on.
The SpaceFlightNow website has the USSF-51 launch now scheduled for the second quarter of 2023.

header changed as as far as I know we have no confirmation on type of Atlas V, 551, 501 or otherwise, except apparently this being tail number AV-101

Sorry if this has already been discussed. I did not find it.

apparently, Congress directed USSF to stop using Altas by 2022.

So how can USSF-51 and NROL-107 fly on Atlas V in 2023?

Because they understand the difference between production cutoffs and mission delays

Missions were delayed beyond their original target launch date. The above applies to ordering the launch which predates 2022. The pandemic and other factors delayed many government missions which are not limited to ULA rockets. All Russian components were fully delivered before the deadline meeting the laws requirements.

Notwithstanding the fact that the USSF-51 was intended to launch on a Vulcan before delays into manufacture and testing of the BE-4 engine for the Vulcan's first stage prompted the ULA and US Space Force to replace the Vulcan with Atlas V as the launch vehicle for USSF-51, is it possible that the US Space Force could launch USSF-51 in mid-April depending on how soon the CFT mission could launch in April once the SpaceX Crew-5 returns to Earth?

No.
a.  It takes about a month to turn around and launch another Atlas
b.  The spacecraft would have to be at the launch site.

I was just speculating a possible appropriate time in Q2 2023 for the USSF-51 launch because the USSF-51 is scheduled for the second quarter of 2023 as per the SpaceFlightNow website, and the CFT mission will be launched atop the Atlas V in April 2023. Point B you mention is somewhat different than point A because irrespective of whether the first manned Starliner flight takes place early April, there would be sufficient time for the US Space Force to consider a May launch window for the USSF-51.

How do you know that?  Contracts have to be changed for the spacecraft, launch vehicle and processing facility.

Given that NASA is now targeting the middle of April for the first crewed Starliner flight, since you have said that it takes about a month to turn around and launch another Atlas V, the US Space Force might have to wait a few months after April to prepare for launch of the USSF-51 (the NextSpaceFlight website) lists a NET June 2023 launch window for USSF-51, which could be plausible because the Atlas V configuration scheduled to launch the USSF-51 is yet to be decided upon.

It was decided when the launch contract was signed but has yet to be publicly disclosed

Ok, I'll bite, so what configuration does USSF-51 have ? assuming it is public ?

The mission is presently listed on multiple websites as using the AV-551 configuration with the launcher tail serial number
being AV-101.

NSF USA Launch Schedule:
2023
NET June - USSF-51 - Atlas V 551 (AV-101) - Canaveral SLC-41

Example non-NSF reference site: https://space.skyrocket.de/doc_lau_det/atlas-5-551.htm

You guessed 501, against 551. I would argue that they need 551 for the 8,900 kg to GTO or 3,904 GEO because its being bid against Falcon Heavy with DIVH being allocated for its last launches.

USSF-51 seems the only option for this launch:

Stich: know there's another launch on the range about that time. Need to work that with other govt agencies.
