Unable to disable SIP on macOS 27 Beta 1

I work for a company which develops as part of our product suite a System Extension implementing an Endpoint Security client.

Our local developer workflow for testing and validating changes is to build locally with Developer certificates (not a legitimate/production Developer ID certificate) and deploy local builds in to a VM, where to get the System Extension to load and be accepted we need to disable SIP & AMFI.

macOS 27 VM is refusing to allow me to disable SIP.

Is there an alternate approach we can use for this workflow to allow macOS VMs to accept our software when signing with a (same teamID, but different certificate to the provisioningprofile) developer certificate for local validation?
