xe.enable_display is called xe.probe_display since commit 1eda95cba9df
("drm/xe: Rename enable_display module param") to reduce the confusion
between the two params.
xe.probe_display=0 will give you a "truly display free test run", but
you just can't properly test suspend/resume like that. If the hardware
has display IP, it just won't magically go to sleep if you don't touch
it.
Looks like the premise of the test is flawed.

Jani.
