how to get access to nw-linux again

[X0r9ix]

Hi, I want to know how to get access to normal world linux again after "./launch.sh", using tf-rmm and fvp
#42 mentioned that it's impossible to exit from realm to nw-linux
But I just want to get access to the control of nw-linux again
so is there any method to close the realm
I'm not familiar with the using of fvp, so I'm not sure if it can be simply done by fvp, Maybe like lauching realm in a new terminal so terminal for nw-linux can be used to close the realm
