Message signaled interrupts

[yato]

I want to disable message signaled interrupts for intel iris xe graphics on my laptop for some reasons but when I disable it gives error and does not load the driver on reboot or on device manager disable and enable is there a way to make it use line based interrupts instead of msi? I see the option line based on msi utility but it doesnt work for some reasons probably interrupt priority handling etc. can someone help me make it line based interrupts
thanks
