Nomodeset disables KMS for all graphics hardware. The moniker i915 for the
kernel's Intel support module is derived from a specific Intel graphics version
from around 17 or so years ago. So, e.g. i915.modeset=0 limits disabling of KMS
to
Intel IGPs, like amdgpu.modeset=0 disables only for AMD GPUs, and
nouveau.modeset=0 disables KMS only for NVidia GPUs. KMS either is or isn't
enabled. There's no in between. Disabling makes X performance dismal, except
when
using non-FOSS drivers that don't depend on KMS.

Nomodeset is primarily intended to be a troubleshooting parameter. KMS, which
nomodeset disables, is an absolute requirement for competent graphics
performance
from al FOSS drivers supporting AMD, Intel and NVidia GPUs, among others.
