Is it possible to “go back” to grub after booting linux

I am trying to enable secureboot so I can forget about it when switching between windows and linux through dualboot. However, grubs newer versions don’t allow mods to be inserted after boot, so I need to be able to find the modules that grub uses after linux has been booted so I can add them to the grub compilation command. How can I do this? Can I return to the grub command line after booting linux to run lsmod?
