While using X11 all is perfect although I override edid using the following:

/etc/X11/xorg.conf.d/00-nvidia.conf

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "Stereo" "0"
    Option         "nvidiaXineramaInfoOrder" "DFP-2"
    Option         "metamodes" "3840x2160_120 +0+0 {AllowGSYNCCompatible=On}"
    Option         "SLI" "Off"
    Option         "CustomEDID" "HDMI-0:/usr/lib/firmware/lg.bin"
    Option         "MultiGPU" "Off"
    Option         "BaseMosaic" "off"
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

Section "Device"
        Identifier      "3090"
        Driver          "nvidia"
        Option          "ModeValidation" "AllowNonEdidModes"
EndSection

Yeap, you are correct. drm_info shows vrr_capable 0 with override. 

This is my service.

[Unit]
Description=EDID Override Service
Before=sddm.service
RequiresMountsFor=/usr/lib/firmware/edid/lg.bin

[Service]
Type=oneshot
ExecStart=/bin/sh -c 'for edid_path in
/sys/kernel/debug/dri/*/HDMI-A-1/edid_override; do if [ -f "$edid_path" ]; then
cat /usr/lib/firmware/edid/lg.bin > "$edid_path"; fi; done'
RemainAfterExit=true

[Install]
WantedBy=multi-user.target

-------------------------------------

Any suggestions on how to fix this for wayland ? edid override on X11 works ok.
I presume open a bug report on nvidia forums would be where to start.
