Hi.
Looking at the schematic I realized there might be some hardware change needed to support these faster modes for SD... take this new schematic from Espressif as reference: https://docs.espressif.com/projects/esp-dev-kits/en/latest/esp32p4/_static/esp32-p4-function-ev-board/schematics/esp32-p4-function-ev-board-schematics_v1.5.1.pdf

I would have loved testing UHS-I 1.8V modes with your board but seems like that it has the same design like the 1.4 rev of the official Eval board.
