[ovirt-users] Add Gluster only nodes?

Hello! We have a medium sized hyper converged setup where we run SSD based bricks on the hosts. we also have an iscsi storage domain towards some spinner boxes for slow bulk storage but now we would like to add an medium sized storage option where mid sized requirements and mid level I/O requirements can exist. Our hyperconverged is NVME Our spinner is Sata. We now want to add an sata SSD storage option. We have some 25 slot hosts that are going to fill this usecase and we are now wondering, is there a way we can deploy gluster on these nodes using ovirt without giving them the VM role? Due to this storage being aimed towards things such as databases and other intensive (But not as intensive as our NVME layer) use cases we dont want there to be any VM load on these machines because of the pure number of bricks on the machines and the redhat best practice of 1 core per brick. Can i use cockpit/ovirt to deploy the above or do i have to set up an gluster cluster manually and then add it to ovirt???
