Sure thing. I have been running with "nvme_core.default_ps_max_latency_us=250" and repo kernel for about 24 hours now without issue. Confirmed with nvme that APST is enabled. I will switch to "nvme_core.default_ps_max_latency_us=3000" later today or tomorrow.

$ sudo nvme get-feature -f 0x0c -H /dev/nvme0
get-feature:0xc (Autonomous Power State Transition), Current value:0x000001
 Autonomous Power State Transition Enable (APSTE): Enabled
