Enable Specific MFA Provider

Let’s say I have all Auth0’s default MFAs enabled on my dashboard and I am running a B2B application where my customer’s employees will have to log in to my application.

I want my customer (the employer) to be able to set a configurable MFA policy for all of their employees. Let’s say customer A would like to require all of their employees to use OTP but customer B would like to only allow SMS.

I can’t see a way to do this with actions because the MFA provider is “any”. Is there anything I can do to help my customers create highly configurable MFA policies for their employees logging in to my application (and still use universal login)?
