hello sebastian-uav2022,

please refer to below for Orin uart mappings.
for example,

pin# signal name ball name GPIO software customer usage
K53 UART1_TX UART1_TX GPIO3_PR.02 UART-A / serial@3100000 40-pin header Pin 8 GPIO/UART1_TXD
J58 UART5_TX UART2_TX GPIO3_PX.04 UART-B / serial@3110000 M.2
H62 UART3_TX_DEBUG UART3_TX GPIO3_PCC.05 UART-C / serial@c280000 Primary Unified Debug UART
L5 UART4_TX UART4_TX GPIO3_PH.03 UART-D / serial@3130000
C58 UART2_TX UART5_TX GPIO3_PY.05 reserved secondary debug UART

you may see-also sysfs, please visit pinconf-groups for checking uart functions.
for example,

# cat /sys/kernel/debug/pinctrl/2430000.pinmux/pinconf-groups | grep uart
2 (uart3_tx_pcc5):
        func=uartc
120 (uart2_tx_px4):
        func=uartb
155 (uart1_tx_pr2):
        func=uarta
