I wanted to drop my own answer here as it did seem each answer has parts of a correct answer and some details can be found in comments only.

In this example I have 2 file system mounts in /var/www/mymount1 and /var/www/mymount2

This part of my Vagrantfile:

config.vm.provision "shell", path: "docs/vagrant/init-vagrant.sh"
config.vm.synced_folder "mymount1", "/var/www/mymount1", type: "nfs"
config.vm.synced_folder "mymount2", "/var/www/mymount2", type: "nfs"

I am placing the script below in /docs/vagrant/init-vagrant.sh as its my provisioner file.

# Copy nginx systemd script and make edits in /etc/systemd/system, as updates might change the original in /lib/systemd/system/nginx.service
cp /lib/systemd/system/nginx.service /etc/systemd/system/
# These tell that nginx should not be started before file system mounts are available
echo WantedBy=var-www-mymount1.mount >> /etc/systemd/system/nginx.service
echo WantedBy=var-www-mymount2.mount >> /etc/systemd/system/nginx.service

# Update service symlinks
systemctl daemon-reload
systemctl disable nginx.service
systemctl enable nginx.service
