Can a pharmacist remove this type of cap or how can I do it at home?

Yes, there are different options you can try to remove the blockage in your ear. You can use warm oil to help dissolve the wax, or you can try a product like Cerumol that is available at pharmacies. Another option is to have a healthcare professional, like a nurse, remove the blockage using a special technique. It's important to follow the instructions carefully and seek medical help if needed.
