This may be the next launch from Xichang--see "Chinese launch schedule" thread discussion, starting here.

A CZ-3B, with no YZ-1 upper stage, is assembled at XSLC.

I think it's LC 2.

I think it's LC 2.

That would be LC2 as LC3 has a crane on top of the adjacent service structure with no mobile service structure to assemble the rocket while LC2 uses the mobile service structure to assemble the rocket as seen in the above images. Also LC2 was used for the launch of the first BeiDou-3 GEO sat back in November of 2018.

Have there been any NOTAMs for this launch yet?

Not yet, and looks like the launch was postponed. Don't know the reason.

The discussion up-thread of the LV on LC2 could have been for Beidou-3 I1Q instead; discussion thread here.

According to spaceflightfans.cn, this will launch on April 19 or 20 (TBD) on a CZ-3B:

地点:中国四川西昌卫星发射中心(XSLC)
火箭:长征三号乙/改2(CZ-3B/G2)
载荷:北斗三号G2(Beidou-3-G2)
客户:国家航天局(CNSA)
轨道:地球同步转移轨道(GTO)

(Earlier they had reported Beidou-3 I1Q for that launch.)

A1662/19 - blue
A1663/19 - red

.....and these are standard GTO trajectory drop zones, not the 55 degrees inclination we have expected.  :-X

Beidou-3 G1 has a 3° inclination:

1 43683U 18085A   19107.96270309 -.00000270 +00000-0 +00000-0 0  9990
2 43683 002.7174 270.6914 0001126 089.5964 336.6152 01.00270086001828

So this drop zones can be ok for G2. spaceflightfans.cn also shows it as Beidou-3 G2Q:
