Samsung S9+ frozen won't factory reset

I have a Samsung Galaxy S9+ only a few weeks old & only used for a little over a week yesterday it froze on me it turns on & off fine & boots to the start screen but once there it only shows the status bar, notification bar at the top & the back arrow on the screen on the bottom left the rest is completely black. I can still click on "items" & notifications but can't see a thing on the page. I can open settings but can't see where to go in it. I have tried several times to factory reset from recovery mode at startup & it won't let me saying mdm does not allow factory reset & proceeds to normally reboot the phone. I have tried starting in safe mode but again the screen is black so it doesn't help. Is there a way to factory reset from a attached physical keyboard? Or ANY other way?? PLease HELP

Hold power button and Volume up button for 10 seconds until the recovery screen appears then use volume down to scroll down to clear cache then volume up to scroll up to reboot. then see the magic.
