How to set HDMI Port 1 to be used by default on Pi4?

Question

During some experiments it looks like my HDMI port 0 broke down. I still can SSH to it.

tvservice -M <display on port 0>

Does not show any activity on port 0 when I plug the HDMI cable in and out. However doing this with HDMI port 1 clearly shows that attach and detach the cable.

However, on port one nothing is displayed. How do I tell my pi to solely use HDMI port 1?

Try adding the line

framebuffer_priority=7

to /boot/config.txt .
