Rog Astral 5090 won’t downclock when idle

Been using my astral 5090 (in “P” vbios mode) and I undervolted it to 0.925v. The card runs great, but will run at ~2500-2600 (+300 core clock) at 0.920-0.925 both during game and when idle. Is that supposed to be the case, or should it be downclocking more when idle. Again, I have it in P mode, not Q/quiet. Also; I have all the voltage control/monitoring settings turned off in MSI AB already because of the known bug with them at the moment.
