Serial cable for radioddity gd77/tyt-md380/similar?

Are there serial programming cables for radios like the Radioddity GD77 or the TYT MD 380 that have a K1 connector, but aren’t compatible with the Baofeng serial cables? These radios have the serial-to-usb chip on the radio, and the cable is just a pass through (unlike the Baofeng cables, which include a usb-to-serial chip in the cable itself).

I believe some Anytone HTs have similar arrangement. I can add K1 to USB cable to the store. Not sure how much demand there is for something like that.

If more people need these, please post here.
