If you are on Debian or Ubuntu you can use

dpkg -x grub-efi-riscv64-unsigned_2.12-5ubuntu5.1_riscv64.deb target_dir

for extraction.

On other distros

ar -x grub-efi-riscv64-unsigned_2.12-5ubuntu5.1_riscv64.deb
mkdir -p target_dir
tar --zstd -xf data.tar.zst -C target_dir

target_dir/usr/lib/grub/riscv64-efi/monolithic/grubnetriscv64.efi
is the file I am using. That one has all the network modules included.

Best regards
