Specific Can you sharpen this image without adding noise?

[muutlik]

I would like this image to be clearer but sharpening it only makes the quality worse since it adds too much noise. I don't even know if it's possible to make it really clear, but at least can anyone make it a little bit better?

Thanks!

Tried with a high pass filter set to hard light with a radius of 3


Same settings but with linear light


You are right though it is tricky.
