restrict file / image fields in vendor registration

Hello how are you? I hope that very good . I apologized for the inconvenience

I have a query, I would like to know if the file / image fields that I can add for the sellers registration, will then be shown in my wcfm or wordpress administration panel to be able to see and save the image that the sellers attach.

On the other hand, is it possible to restrict the file / image fields to loading images only in jpg or png format?

from what I saw so far in the file / image field you can upload all of which seems very dangerous to me, I already have codes to restrict all file uploads but it works for users and in the seller registration fields it does not give me Outcome.

I appreciate your response, thank you very much in advance.
