Can someone confirm if this is Anthracnose of Pepper?

Thanks but b the pants are in a protected greenhouse. Is it still possible to get Sun burnt?

Yes very common disorder in Polyhouse

Blossom End Rot avoid the plant from water deficiency so the with more water uptake the calcium will be available easily to plant and problem will be covered

yeah Narenpalsingh, Much close to Blossom End Rot

This is due to high temp or come n contact with direct sun light I had experience which was planted in open filed just for experience.

Thank you all. Are there any prevention measures or treatment steps?

Most likely blossom end rot. Calcium insufficiency in the soil leads to that
