MacPro 5.1 won't boot with GT 710 on Monterey

I have Monterey installed on my MacPro 5.1 and would like to add a GT 710, which I remember was previously possible with root patches on Monterey. But when I install the GT 710, the Mac no longer boots and I cannot install the Kepler root patches without installing the GT 710. Is there a way to fix the problem?

Many thanks for your help!
