No, you need to tell the kernel to load the custom edid (userspace is
not allowed to modify it otherwise). Look at the
drm_kms_helper.edid_firmware= module parameter. You basically save the
edid you want to use into /lib/firmware/my-edid.bin, then tell the
kernel to load it for your connector like
drm_kms_helper.edid_firmware=HDMI-A-1:my-edid.bin

Hope this helps,
