we simply use this within our wrapper script:

$START_WITH -c "/usr/sbin/fai-chboot -$CHBOOT_OPTS -k'console=$TTY 
nomodeset modprobe.blacklist=$MODPROBE_BLACKLIST' -f $FAI_OPTS 
-s$KERNEL_VERS -u nfs://$FAI_SERVER_IP/srv/fai/config $TARGET_IP"

and those entries do make it into the pxe file:

append initrd=initrd.img-4.19.0-10-amd64 ip=dhcp 
root= rootovl console=tty0 nomodeset 

Thus, it ought to be straight-forward
