Rock 4se uart issue

Hi,

i have a problem with rock 4se. Im using two UART devices which are connected to UART2 and UART4 on rock 4se. The devices are constantly streaming data as soon as booted up. Normally the UART is working but when i restart the rockpi with my UART devices connected to rockpi4se the rockpi doesnt boot. I think its mainly because of serial console on ttys2. Is there any way i can disable it, in order to boot the rock pi without any issue, even when my devices are connected.

Best Regards,
Sarng
