I use ND-Framework. It uses fivem-appearance but the options for whether peds are offered in the character selection are set in the configuration of the clothing shops themselves.
Allow me to restate. I do not use qbcore. I have no idea how to set this up in your framework. I have no intention of reading the documentation for qbcore to learn how to set this up simply to teach you.
I am sorry I could not help you. Our time here is complete.
