In order to disable the "temporary addon" button, you would need to disable the installation of any addons.

To do that, you can use ExtensionSettings. (https://mozilla.github.io/policy-templates/#extensionsettings)

It doesn't look like policy generator supports any complex stuff, so after you create the JSON, add a section that looks like this:

"ExtensionSettings": {

 "*": {
   "installation_mode": "blocked"
 }

}
