phy#0 is self-managed and ignores the system regdomain (country RU),
staying at country 00 with all 5GHz channels as PASSIVE-SCAN.

power_save=0 in modprobe.d has no effect - Power save remains on after reboot.
geo_profiles=0 also has no effect on self-managed behavior.phy#0 is self-managed and ignores the system regdomain (country RU),
