Hi Christian
pinmux settings are given in Table 8-1. ROM Bootloader Peripheral PinMux
i.MX RT1050 Processor Reference Manual
Boot mode only using fuse mode as shows Table 8-35 (there is no GPIO override mode),
fuse selections are given in Table 5-9. Fusemap Descriptions i.MX RT1050 Processor
Reference Manual

Best regards
igor
