I don't think that it's switcheroo-control's job to disable rhgb to work-around a kernel bug. I would advise reaching out to Lukas Wunner (listed in the kernel's MAINTAINERS
file) so he can help diagnose and fix those problems.
If the system boots on igd with grub set to "rhgb", then display-manager will not start and system locks (even if you OFF the discreet card, or leave it enabled)
As a result, the only method to boot is to remove rhgb from grub to prevent display change issues.
switcheroo-control should disable "rhgb" on systems to prevent display locking issues on startup.
