If you want to know the frames detected by SCDetect() using Hybrid, the only way that I know is to use HAVC.
Try the following code

P.S.
If you fix the issue that I reported today on HAVC you will be able to do it from the Hybrid GUI
Try the following code
from vsdeoldify import HAVC_ddeoldify, HAVC_deepex
clipRef = HAVC_ddeoldify(clip=clip, method=1, ddtweak=False, sc_threshold=0.1)
clip = HAVC_deepex(clip=clip, clip_ref=clipRef, method=0, sc_framedir="path_to_debug_frames", only_ref_frames=True)
