Workaround that will stop the race condition was backported to 252.1:

https://github.com/systemd/systemd-stable/commit/1757446e8bc4dc076badd5c1ad53a0021c42638c

No need for a conflict, for the next release we'll fix it to force
using the kernel driver as the default. On old systems with older tpms
the userspace manager might be needed for late-boot stuff, which is a
legitimate use case. It's the early-boot usage that is a problem.
