For Bitcoin-only support see BitBox02 Bitcoin-only edition
It is not possible to convert a BitBox02 Multi edition into a BitBox02 Bitcoin-only edition or vice-versa. The BitBox02 bootloader prevents firmware downgrades and installing firmware for a different edition of the BitBox02 (Multi or Bitcoin-only) as otherwise that would be a security attack vector.
