Disabling cache for external SPI RAM

I am using the external SPI RAM on WROVER Kit rev3 for a display buffer.
So is it possible to disable external SPI ram caching but keep it memory mapped.
Alternatively, is there a uncached mapping for the external SPI RAM.

No, external memory on the ESP32 can only be mapped into the address space via the cache.
