How to remove payment methods completely in Magento Checkout/Shipping page

[ntquy9901gf2c4]

I want to remove 2 payment methods Mercado Pago and CyberSource completely in Magento. After I tried to disable them in the Admin page, then open Checkout/Shipping page, APIs or requests of Mercado Pago and Cybersource are still called (I observed APIs and requests calls via Chrome devtools / Network). Is there any way to remove completely them from Checkout/shipping page?

Those are both probably some 3rd party extensions. You should completely remove them. They are either installed through composer or added through app/code/
