How do I remove a certificate from (RedHat) Linux ca-trust?

I installed a duplicate certificate for a CN in the ca-trust store of my RHEL8 systems. I added the PEM file to /etc/pki/ca-trust/source/anchors and ran update-ca-trust.

How can I remove the certificate(s) that update-ca-trust installed? It seems that it only adds to the stores and doesn’t delete.
