Changing Resolution and quality of Anti-Aliasing

Hey, it's my first post so I'm not super familiar with the rules but I've sure did my research before I start a new topic.
So, my question is about Reshade Anti-Aliasing and Sharpening filters, namely FXAA, SMAA and AdaptiveSharpen (Lumasharpen sometimes).
I'm not a big fan of MSAA in new-ish games as they only increase the geometry and leave the textures and shadow/lightning renders untouched. Especially in TXAA supported titles, LOD bias is forced to high negative values so making the aliasing much more apparent.

My question is; is it possible to tell Reshade or specifically, FXAA and SMAA to run out of the actual resolution. For example, can I tell it to run in a resolution which is a coefficient of my screen resolution, like 2*Height and 2* Width?

I believe this is what game consoles do, too? Because they render the game in lower resolutions but apply the post processing effects at higher resolutions like 4K.

Thanks in advance

That's not how it works. Reshade can only see and operate on the output resolution that is given to it.

Marty McFly has mentioned it here before, but never told how to achieve it.
