K3S install script is ignoring the whole environment variable for some reason. Anyone can help?

Your initial " should be before the --

Sorry, I copy pasted that double quotes and it was a mistake that was put there. In the actual line of code the quotation is before the --.

Sorry for the confusion. this is the actual code which k3s is ignoring.
