Impact of Atlas V retirement on the X-37B

[Vahe231991]

The Boeing X-37B has been launched atop the Atlas V on all of its orbital missions, but at the current time of writing, the three remaining Atlas V missions for the US Space Force do not have the X-37B assigned to those missions. Since the last  Atlas V mission for the US military is scheduled for this year, is it possible that ULA is investigating possibly using the Vulcan rocket to loft the X-37B into orbit, since the Vulcan rocket's payload fairing width is the same as that of the Atlas V and thus big enough to accommodate the X-37B?
