Description
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.

Research direction
Start by comparing the board schematic with the linked ESP32-P4 Function EV Board schematic v1.5.1 and review the ESP-IDF SDMMC supported speed modes page. Done means establishing whether this board can support SDMMC UHS-I 1.8V modes and documenting the required hardware change, if any.
