So I wouldn't recommend removing the in game sharpening filter. SMAA and FXAA will not do sufficient in any way on their own for this game. There is just too much raw aliasing generated from every part of the engine. (Textures, lighting, shading,geometry,dithering, standard undersampling issues of subpixel information). The TAA and sharpening are needed. And the in game sharpening when applied to the TAA does a far better job of recovering information without adding excessive artifacts than reshade sharpening solutions alone.
I would recommend using a light sharpening pass on top of the in game sharpening with TAA+FXAA with Reshade. Along with disabling Lens distortion (makes the image even blurrier), and screen space reflections. SSR absolutely wrecks the IQ in this game. It is absurdly low quality and adds a bunch of ghosting and smearing to the image where ever it is used beyond pools of water. Turning shadows down to High, and volumetric lighting to medium can save a lot of performance.
If you have the option and extra headroom I would also recommend you also use downsampling on top. DSR/VSR have a much better resolve filter than the in game resolution scaling (probably a basic linear resolve). But the in game resolution scale is a lot sharper than DSR by default. And with sharpening on top it will look just that much sharper.
I can't stress enough how much downsampling on top makes a difference in this engine with the TAA, much like RE7. If your GPU can handle it 150% resolution scale in game or 2.25x DSR (Which is equivalent to 150% in game as 2.25x is 1.5 of each axis. Resulting in an actual 225% difference in resolution) as a good middle ground.
(In some examples below I use Reshade FXAA over the TAA only option Instead of the in game TAA+FXAA as the in game FXAA doesn't do a good job of cleaning up the edge quality)

Image quality comparison.
We want the No AA image without the built in sharpening as our baseline of how the game should look. (As it should be disabled without TAA enabled. But it isn't)
No AA (No sharpening in game)

But when it's still enabled without AA enabled, it causes a false impression that the final TAA option in the game is much blurrier than it is actually intended to be. As the sharpening+No AA causes a hugely disproportionate impression of how the game actually looks without AA.
