Need help with glass material

Question

I was making a pinart in blender which is covered by glass or plastic. I used an hdri to light the scene.

But the problem is that the glass is reflecting the lights of the hdri and also giving a black tint to the board

With Glass:

Without Glass:

My question is how do I get rid of the reflecting hdri? Also is the black tint due to noise in the glass? Is there a way to fix these problems. I guess a light path node would help but I was not able to fix it.

Thanks in advance

I already tried this. This didn't work as on the edges of the glass you can clearly see that white color — Maulik Sharma, Aug 03 '21 at 18:00

Yes this fixed the black tint problem but how do I get rid of light reflection from the hdri — Maulik Sharma, Aug 03 '21 at 18:25

Instead of Principled or Glass BSDF, you might try Refraction BSDF.

Here is a mix that gives you a very slight amount of light source reflection. You have to go very close to 1 to get any meaningful reduction.

The full solution probably looks like this:
