Having issues turning on HDR with a two monitor 4 computer KVM

I have a desktop with a RTX 3090, and two monitors connected to a Level1tech kvm switch. One monitor is hdr enabled and the other is not. If I have both monitors connected then I am unable to turn on HDR (it just turns back off immediately once it’s enabled). If I unplug the non-hdr monitor and restart my PC then I am able to turn hdr on. I would like some help troubleshooting these issues. I would like to be able to use both monitors with hdr enabled on my hdr capable monitor.

Are you using mirror or extend? HDMI or Displayport? and what version does your cable support?

Im using extend and display port 1.4 cables from kvm to monitor and kvm to gpu.

What model monitor is your HDR one?
