TX2NX THS1 pixhawk not working

Leetop A203V3.1 Tx2NX pixhawk on /dev/ttyTHS1 pin 8,9,10
In our usecase we are trying to use THS1 on tx2nx pin (8-10) on 40pin header to connect to pixhawk
But even after removing serial=<3> from bpmp dtb and enabling THS2 still not able to send recv data on THS1 we are using jetpack 4.6.1

Please help
