Yes. In ExifTool, use the advanced formatting syntax on the tag: add a semicolon after Model inside the braces.

Example: -FileName<${Model;}-(%f).%e

The ; tells ExifTool to delete characters that are invalid in Windows filenames from the tag value, so a model like KENOX S860 / Samsung S860 won’t be interpreted as a directory path.

You can combine this with your date-based rename as needed. If you need more custom cleanup than just removing invalid filename characters, another approach is to define a user tag based on EXIF:Model or preprocess the model name in your batch script before renaming.

But for your specific slash problem, ${Model;} is the straightforward ExifTool solution.
