All the newest ESP32 variants for a bit now have been RISC-V. The last new LX7 was the ESP32-S3 (in fact, the S2 is the only other LX7), and LX6 is basically a legacy product that only lives on in the [non-variant] ESP32. The P4, the entire C and H series, and the new S31, are all RISC-V cores. Not to mention that RISC-V has even taken over for Espressif's classic ULP cores in all the same places (and even lives alongside it in the two LX7-based chips). They're well beyond "fiddling" with it.
