Hi @papai40515,
The sure fire way to disable the PayPal tab from WooCommerce → Settings → Payments is to disable the PayPal plugin. From what I can tell, you don’t want to disable it, instead, you want to hide it from that page.
To do that would require some custom code to be written. If you’re looking for custom code help, you might be able to find someone willing to volunteer their time and knowledge in the free PHP support forum at PHP Builder, or within the Advanced WooCommerce group on Facebook.
For assistance with customization or development with your site, we recommend reaching out to someone on our customizations page.
