How to Boot ESXi 7.0 on UCS-M2-HWRAID Boot-Optimized M.2 RAID Controller

VMware strongly advises that you move away completely from using SD card/USB as a boot device option on any future server hardware.

SD cards can continue to be used for the bootbank partition provided that a separate persistent local device to store the OSDATA partition (32GB min., 128GB recommended) is available in the host.
Preferably, the SD cards should be replaced with an M.2 or another local persistent device as the standalone boot option.
