Are there any examples for hardware filters?

cmd = [
        'ffmpeg', '-y',
        '-init_hw_device', 'd3d11va=dx', 
        '-init_hw_device', 'qsv=hw@dx', 
        '-filter_hw_device', 'hw',
        '-hwaccel', 'qsv',
        '-hwaccel_output_format', 'qsv',
        '-i', input_path,
        '-i', watermark_path,
        '-filter_complex', (
            f"[0:v]vpp_qsv=w={target_width}:h=-1[bg]; " 
            f"[1:v]format=bgra,hwupload,format=qsv[wm]; "    
            f"[bg][wm]overlay_qsv=x=W-w-10:y=H-h-10" 
        ),
        

        '-c:v', 'h264_qsv',
        '-global_quality', '28',
        '-preset', '4',         
        # '-look_ahead', '1',
        
        '-c:a', 'copy',
        output_path
    ]

Pyav can do these?
