Linux/PROCESSOR-SDK-AM437X: How to disable UART0 console on am437x gp evm

Part Number:PROCESSOR-SDK-AM437X

Tool/software: Linux

We want to use UART0 for a different purpose on the am437x gp evm.

I have tried the following:

Commented out this part in am437x-gp-evm.dts

/*
    chosen {
        stdout-path = &uart0;
    };
*/

Then in u-boot promt

setenv console null

saveenv

When booting again after this printenv indeed shows

console=null

but console output still goes to uart0. Is there anything else I need to do and is this at all possible ?
