How to modify the purchased template module correctly?

Question

1C-Bitrix

Good afternoon!
A purchased template is installed on the site, I need to modify the module class, along the path /public_html/bitrix/modules/custom_module/
I understand that this cannot be done in the core due to updates. What would be the right thing to do?

Answer 1

move it to your namespace /local/modules/custom_module and modify to your health.
