Possibly. I have some forms that rename photos, but haven't tried it with files. Here's what I have in the bind::esri:parameters column in Survey123 Connect for one of my surveys (bolded for emphasis):
fileName=concat("Prefix", ${Field})
If you just want the file named based on a field, you could use fileName=${Field}
Also, I like to lock things down for consistency, so have used the parameter fileNameVisible=false in the body::esri:style column so that the name can't be accidentally (or purposely) changed by the user.
Hope that helps 😁
