I'm attempting to wake my computer (B550M PRO4 latest bios) from full shutdown using the Windows 10 waketimers (set using Task Scheduler). The timers are set (verified from powercfg /waketimers) and I have enable the bios option of RTC waketimers from OS but nothing happens at the time set. The computer remains in full shutdown.

Setting the RTC wake to a BIOS specified time works and the computer wakes but the from OS setting doesn't seem to function.

I am using a full shutdown (all fast boot options are disabled).

Any ideas?
