How to set additional parameters for letsencrypt

I want to use Public Certificate Authority API instead of Let's Encrypt
but I need to pass a few extra parameters
It looks like this in certbot

certbot register \
    --email "EMAIL_ADDRESS" \
    --no-eff-email \
    --server "SERVER" \
    --eab-kid "EAB_KID" \
    --eab-hmac-key "EAB_HMAC_KEY"

But I can’t find the relevant configuration instructions in gitlab.rb and https://docs.gitlab.com/omnibus/settings/ssl.html#install-custom-public-certificates

How do I set these parameters?
Can anyone give me any help or advice?
