This page details how to add custom certs in a LCP.json file

https://learn.liferay.com/dxp-cloud/latest/en/infrastructure-and-operations/networking/load-balancer.html#custom-ssl

The best practice however is to use a secret and then reference the cert values with a @syntax like:

{
  "key": "@ssl-key-encoded",
  "crt": "@ssl-crt-encoded"
},

The documentation should reflect that this is the preferred way to add a custom cert
