Is it possible to manually reject files in a FileUpload before the form gets submitted?

In a Filament form I have the following field:

FileUpload::make('Files')
            ->acceptedFileTypes(self::$filetypes)
            ->disk('local')
            ->moveFiles()
            ->multiple(true)

Now before the form is submitted I want to validate the uploaded files based on their (original) names.

I have tried using ->rules() but that only takes effekt after submitting the form.

I have also tried using ->afterStateUpdated() like this:

->afterStateUpdated(function($state) {
    foreach($state as $idx => $file) {
        $filename = $file->getClientOriginalName();
        if($filename == 'test.csv') {
            $file->delete();
            unset($state[$idx]);
        }
    }
})

This works for deleting the files and probably would not submit them (I have not tried that)
but it does not update the field state to show that the file has been rejected.

Basically I’d want a $file->reject() method so that my field looks like this. The file in the image was rejected due to its size, so there must be a way to validate the files before submission.
