Disable TLS 1.0/1.1 for R2 subdomain

We need to disable TLS 1.0 and 1.1 for our subdomains that are served by R2. We configured this at the top level for *.ourdomain.com but that doesn’t seem to be applying to the R2 subdomains.

Is there a way to do this?

Like your custom domains for R2 or the r2.dev domain?

Our own domains.

Have you set the minimum TLS version under SSL?
