Can I use STM32F301 PA7 and Pb0 as normal AD input and disable opamp on STM32F301?

I do not want to use internal opamp. Layout is already connected to PA7 and PB0 for current sensing and I want to use these two inputs as normal AD input. Can I do that or should I use 'opamp' mode, set gain to 1 and manage switching of opamp input?
