Remove Azure Analysis Services Firewall Rule in DevOps

Question

During a deployment, Azure DevOps creates a firewall rule when deploying to Azure Analysis Services (AAS), like so: 

There is an option in the 'Azure Analysis Service Deployment' task to not delete the firewall once deployed:

I uncheck this as it allows me to run Powershell against the AAS database after the deployment task (to amend the AD groups inside roles per environment, for example). DevOps has a whole host of dynamic IPs that change weekly and don't appear to match IP lists they send out in the weekly file either (that I've seen, plus amending firewall ranges weekly really is overly cumbersome), so I let the rule sit there whilst I complete my subsequent Powershell scripts.

There is a Powershell cmdlet to create a rule in the AAS firewall called 'New-AzAnalysisServicesFirewallRule'.

However, true to their remarkably consistent form for only giving us the tools we really need, there does not appear to be a 'Remove' equivalent which obviously I would like to run to clean it up at the end. I can't see anything in the Azure REST APIs for it either. Consequently, I am manually deleting the rule in the admin portal post-deployment.

There must be some functionality to do it, hence there is a checkbox for me to re-enable should I so choose. I wonder if anyone has uncovered the secret to programmatically removing an AAS firewall rule (specifically of the vsts-release-aas-rule variety) that they could share?
