Just edit:

/boot/uEnv.txt

/uEnv.txt is just a shim..

"/uEnv.txt" will set your bootargs like so:

setenv bootargs console=tty0 console=\${console} \${optargs}
\${cape_disable} \${cape_enable} root=/dev/mmcblk0p1
rootfstype=\${mmcrootfstype} \${cmdline}

So override any of those "\${var}" by defining them in /boot/uEnv.txt
