Advanced users • Using DRM library with Wayland or X (graphical) running?

On RPI 5, can my program display on HDMI 2 while Wayland or X (graphical.target mode) is using HDMI 1? My program displays on HDMI 2 when booted to CLI (multi-user.target), but when I boot to graphical I get no output. It was configured so graphical only uses HDMI 1. All the DRM functions appear to work normally, e.g. drmModeGetConnector,() drmModeGetResources(), drmModeGetEncoder(), drmModeGetCrtc(), drmModeAddFB(), etc. but I get no output.

Can this be done? If so, how to configure?

Thanks in advance!
