On the ARM architecture, where is the location of the grub boot loader. I need to complete disabling ipv6 since xRDP likes to bind to it and I have no use for the protocol for my instance. Kali 2021.3 ARM on a Pi4.
I tried grep -irn 'grub' / found lots of files but not the one I need. Unless there is another way to completely disable IPv6 besides the standard sysctl.conf settings.

Thank you in advance
