Is it now possible to program the Tensilica Xtensa LX6 inside the ESP32 using Assembly Language?

If so what IDE and process to compile and upload the object code to the ESP32/Xtensa LX6 ?

Thanks for any help.

PS - Searched this online but stuff I found was several years old so I'm looking for current status.

Long story short: Yes. You can use ESP-IDF; if you put a .S file in as a source, the assembler should pick it up and link it into the rest of the program.
