How can I change the resolution for DRM?

I need to change the standard resolution for my DRM mode. How can I achieve that?

When I do cat on

cat /sys/class/drm/card0/card0-HDMI-A-1/modes 1920x1080 1920x1080 1920x1080 1280x720 1280x720 1280x720 720x576 720x576 720x480 720x480

The problem is my HDMI screen cannot support 1920x1080. My HDMI screen support 1280x720 and below.

So how can I tell DRM to not use 1920x1080?
