I don't think Shimano makes any clutched derailleurs for fewer than 10 speeds, but there's no technical reason that it can't be done. It looks like MicroSHIFT makes clutched 8-speed and 9-speed derailleurs for their Acolyte and ADVENT groupsets, and they offer variants for use in both 1x drivetrains and multi-ring drivetrains.
