FedRAMP has published guidance about the new NIST password/identity

They note that the formal baseline is still not updated, but encourage
folks to follow NIST's new guidance regardless:

NOTE: At the time of this document’s publication, FedRAMP Moderate and High
controls IA-5 (g)
and IA-5 (1) (a,d) are known to be more restrictive than the new password
requirements in 800-
63B, AAL2 and AAL3 respectively. FedRAMP recommends Agency AOs accept
compliance with
NIST’s guidance that is most up-to-date and consistent with current cyber
security threats. This
may be done using an implementation status of “Alternative Implementation.”

I also confirmed with the FedRAMP program that the baseline is expected to
be updated to match NIST's SP 800-63, and thus avoid the need for any
special acceptance. But the point is that FedRAMP is not an obstacle to
dropping password rotation -- they are expecting service providers to
follow NIST's guidance and drop it.
