How to disable SeLinux labelling for specific runtime?

[anthops]

I'm using gVisor in K3s, which is incompatible with SeLinux. If I use the following config to add my gVisor runtime:

[plugins."io.containerd.runtime.v1.linux"]
  shim_debug = true
[plugins."io.containerd.cri.v1.runtime".containerd.runtimes.runsc]
  runtime_type = "io.containerd.runsc.v1"

I can get it to work by coupling it with:

[plugins.'io.containerd.cri.v1.runtime']
    enable_selinux = false

but that obviously disables it for the whole node. I was wondering if there was a way to disable SeLinux labelling for just that runtime, runsc, without disabling it for everything else.

For context, gVisor tests for labels here: https://github.com/google/gvisor/blob/master/runsc/specutils/specutils.go#L150. Maybe there's a way I could pass SelinuxLabel = "" ? I'm unsure where that'd be though
