Unable to disable vignette while testing via Meta Horizon Link

I'm developing a VR game in a Unity project created through Meta Quest Developer Hub (MQDH).

When using Meta Horizon Link for play testing, a vignette effect seems to be applied automatically, even though vignette is disabled in my application settings.

Is there any way to completely disable the vignette while testing with Meta Horizon Link?
