Removing PayPal or Braintree payment methods from your Magento setup is generally safe, as long as these payment methods are not integrated with other functionalities or modules in your system.
- Check for Dependencies: Before removing, ensure that no other modules or custom functionalities depend on PayPal or Braintree. Sometimes, custom modules might have dependencies or integrations with these payment services.
- Alternative Payment Methods: Ensure you have alternative payment methods configured and working properly. This is crucial to not disrupt the customer's ability to make purchases.
If what you are looking for is "mainly reduce unnecessary things in admin", you can hide specific parts of the Magento admin panel from certain user roles. Magento provides a role-based permission system that allows you to control access to different areas of the admin panel:
- Create or Edit a User Role: In the Magento admin panel, go to System > Permissions > User Roles.
Here, you can create a new role or edit an existing one. When creating a new role, give it a name that clearly identifies the users or group of users it is intended for. - Configure Permissions for the Role:
Within the role settings, you will find the Role Resources section.
In this section, you can choose the resources (areas of the admin panel) that this role will have access to. Magento allows you to select "All" (all resources) or "Custom" (customize) to specify individual resources.
If you choose "Custom," you will see a list of all available resources in the admin panel. You can expand each section and select or deselect specific resources. - Assign Users to the Role:
After configuring the role, you need to assign users to this role.
Go to System > Permissions > All Users.
Edit the users you want to assign to the role or create new users and assign them the newly configured role.
I hope this helps
