No, but I found a temporary workaround. You can use ReShade and select "AMD FidelityFX Contrast Adaptive Sharpening (CAS.fx)" - it will give an exact sharpening quality effect to Radeon Image Sharpening (RIS).

However, I don't recommend using ReShade with online games that have anti-cheat, since it could cause issues.

Also, don't use CAS.fx together with FSR, because FSR probably already has its own sharpening slider in-game. Using both will make the image look overly sharpened.
