The flat bar romance with my gravel bike is over and I want to convert it to drop bars for the cheap

Currently running Shimano 11 speed....... I have Sensah 12 speed on another road bike; I'm on the fence about the SRAM style shift but I like the ergonomics. I'm pretty sure L-Twoo R9/GR9 are compatible but what about Sensah 11 speed?

Sensah team pro is Shimano compatible.
