I updated my monitor to the new firmware 105 and now have Dolby Vision Gaming.  The monitor has not been turned off yet. I even turned the Proximity sensor off.

I just sent my information. Hopefully, this issue will be resolved in the following BIOS or combination with an Asus GPU BIOS update.

You are right. I turned the Proximity sensor off, but the monitor still turned off. I have identified that it turns off less with HDR than with SDR.

I did another firmware flash to test variances between flashing with SDR as default and testing both SDR and HDR after the firmware flash.  If you flash with the latest firmware.  The video display will turn off and then turn off after 3 seconds.  No...

The monitor will still turn off even with the proximity sensor turned off.  With motion, it turns back on after a few seconds.
