[Question]: I'm using rocky 9.7, is it possible to build a vGPU-manager and vGPU-Hostdriver?

I'm using rocky 9.7, is it possible to build a vgpu-manager and vGPU-Hostdriver?

I'm trying to build a vGPU-Manager that includes a vGPU-Hostdriver and use kubevirt with GPU-operator.
However, build-vgpuhost for building vGPU-Host-Driver does not exist.

I'm trying to build with vGPU-Host-Driver and I found that there is rocky9 RULE in the DISTRIBUTIONS variable in Makefile.

# $(VGPU_HOST_DRIVER_BUILD_TARGETS) is in the form of build-vgpuhost-$(DIST)
# The vGPU host driver .run file is assumed to be present in the $SUBDIR/drivers/ directory.
# VGPU_HOST_DRIVER_VERSION must be defined in the environment when invoking this target.
VGPU_HOST_DRIVER_VERSION ?= ""
build-vgpuhost-%: $(if $(VGPU_HOST_DRIVER_VERSION),,$(error "VGPU_HOST_DRIVER_VERSION is not set"))
build-vgpuhost-%: DRIVER_VERSION := $(VGPU_HOST_DRIVER_VERSION)
build-vgpuhost-%: DRIVER_BRANCH = $(word 1,$(subst ., ,${DRIVER_VERSION}))
build-vgpuhost-%: DIST = $(word 3,$(subst -, ,$@))
build-vgpuhost-%: SUBDIR = $(word 3,$(subst -, ,$@))
build-vgpuhost-%: DOCKERFILE = $(CURDIR)/vgpu-manager/$(SUBDIR)/Dockerfile

$(VGPU_HOST_DRIVER_BUILD_TARGETS):

# $(VGPU_HOST_DRIVER_PUSH_TARGETS) is in the form of push-vgpuhost-$(DIST)

rocky9 seems to exist only in normal drivers, not vgpu-host drivers.

build-rocky9%: SUBDIR = rhel9
build-rocky9%: DOCKER_BUILD_ARGS = --build-arg BASE_IMAGE=nvcr.io/nvidia/cuda:13.1.1-base-rockylinux9

Can't rocky9.7 be used as vGPU-Hostdriver?
