That's pretty easy:

# go to wherever your local source code copy is:
cd grass78_git_src/

# fetch diff of pull request:
wget https://github.com/OSGeo/grass/pull/727.diff

# apply diff
git apply 727.diff

# check for the change
git status
# ... this should show: `modified:   vector/v.surf.bspline/main.c`

# compile it
cd vector/v.surf.bspline/
make

# ONLY in case you always do `make install`
# (e.g. I don't since I use it directly from `bin.x86_64-pc-linux-gnu/grass78`)
cd ../../
sudo make install

# to revert the local change (needed after merge of PR, to be able to
locally update):
git apply 727.diff --reverse

HTH,
Markus
