Can you specify what file types a user can upload to a Service Request in HR Help Desk?

Summary:

I know in other modules you can limit what document types can be supported when uploading miscellaneous attachments, but can't see any profile options to control this in Help Desk. For example in Recruiting we can update ORA_IRC_MISC_ATTACH_FILE_TYPES profile value to control the file types added such as .txt, .rtf, .doc, .docx, .pdf, .odt, .jpeg, .png, .HEIC, .pptx, .jpg, .dotx, .potx, .ppsx, .ppt, .pub, .xls, .xlsx

I know there is the CSO_EXTENSIONS_NOT_TO_INDEX profile value, but this is the only one I can see for Service that has any reference to document type.
