Depends on the whether or not the system needs something from the NFS  
mount at boot time. If it doesn't then you would do well to use amd  
(man 8 amd) to handle the mount. The short of is that amd automates  
the process of mounting a filesystem by presenting a directory. When a  
process requests a file within that directory amd performs the mount.  
Amd helps by deferring the mount until something actually needs  
something from the remote filesystem.

Simpler still would be to change the mounts entry to noauto in /etc/ 
fstab. However then you or someone else will have to perform the mount  
when you need the filesystem.
