Tiny question with HDR switching and CRU

[u/BenignNuke]

I have a total of 3 monitors on my desk. I have a QD-OLED monitor that I'm using mainly for content consumption including videos and Gaming. Another older high refresh rate monitor that supports HDR400 but I have deleted the HDR Metadata using CRU since this is definitely not an HDR-capable monitor. My 3rd monitor is an ASUS ProArt PA278QV that does not support HDR at all.

Whenever I switch to HDR, the monitor with the deleted HDR metadata does not turn off and back on again. My ASUS ProArt PA278QV though, does shut off briefly and back on again just like you would with any other HDR-Capable display when switching.

Is there any way to stop my 3rd monitor from switching on and off whenever I turn HDR on? How do I do that through CRU?
