FileUpload with TextInput disabled.

I'm using flysystem google drive adapter however it does not seems to work without custom fileupload, it only managed to store the filename in the db but cant show it because different logic. Before fixing that, i expect a more simple solution. On edit mode, when i add FileUpload fields together with TextInput of filename, it's all empty. But when i only add TextInput it shows the current filename correctly. I want it so that TextInput is disabled and shows current filename in db while the FileUpload field still works on storing the filename to the db (and the disabled TextInput field change accordingly).
