Can OCSP be turned off / disabled?

Is there a flag that allows OCSP to be turned off? I am trying to make caddy work with my CA (sectigo) and I see a note in their documentation that they do not support OCSP so looking for a quick / easy test to see if that is where my problem is.

Caddy automatically disables OCSP stapling for certificates that don’t have OCSP responders specified.
