Deinterlace only the frames flagged as interlaced

No, neither TFMBob nor QTGMC do this.
Hybrid has no automated way for this. (since for me, it never worked reliably)
Something along the line of

def conditionalDeint(n, f, orig, deint):
    if f.props['_Combed']:
        return deint
    else:
        return orig

deint = core.tdm.TDeintMod(clip, order=1, edeint=core.nnedi3.nnedi3(clip, field=1))
combProps = core.tdm.IsCombed(clip)
clip = core.std.FrameEval(clip, functools.partial(conditionalDeint, orig=clip, deint=deint), combProps)

or

clip2clip = clip
def postprocess(n, f, clip, deinterlaced):
  if f.props['_Combed'] > 0:
    return deinterlaced
  else:
    return clip
clip2clip = qtgmc.QTGMC(Input=clip2clip, Preset="fast", TFF=True, FPSDivisor=2)
clip = core.vivtc.VFM(clip=clip, order=1)
clip = core.std.FrameEval(clip=clip, eval=functools.partial(postprocess, clip=clip, deinterlaced=clip2clip), prop_src=clip)

might work.
General idea: create two clips, one (same frame rate deinterlaced), the other ran through TFM or VFM. Then mix them.
