My Mac Book Pro is now stuck after Apple logo screen on a grey screen and after hours of search I found the problem is in my graphic card (this issue happen after updating to High Sierra).
So I need to disable the second VGA
I tried with
/sbin/fsck -fy /
/sbin/mount -uw /
mkdir /Disabled_System_Library_Extensions
cd /Disabled_System_Library_Extensions
mv /System/Library/Extensions/ATI* .
mv /System/Library/Extensions/AMD* .
touch /System/Library/Extensions
exit
but I got an error :
operation not permitted
any idea to fix this or at least disable SIP ?
Notes
I am not able to boot to any GUI neither by safe mode boot nor verbose mode or even recovery mode, so I need to do it via terminal
I am only able to boot via single user mode

The only way to disable SIP is to go in through the recovery partition and disable it from there, so unfortunately I don't think that will be an option for you with the current state of the machine.
I would take a look at the answer for this question here: MacBook Pro How To Disable Discrete GPU Permanently from EFI
Booting into a different OS is probably going to be your best chance at success. Hope that helps!
