Catalina 10.15.6 automatically connecting to NFSv3 shares on Ubuntu 20.04 machine

With this command from terminal I can succesfully connect to NFS share, but how to automate this? sudo mount -t nfs -o nfsvers=3,proto=tcp,resvport 192.168.x.x:/nfsshare /Users/xxx/nfsshare Until now, I was able to connect to NFSv4 shares from Finder's Connect To Server option and then to drag that volume to Login Items in User section of System Preferences, but I had to downgrade Ubuntu's NFS support to v3, because v4 causes freezing of the whole NFS server machine. The same technique for automatic launch of shares is not working with NFSv3. Already tried this: https://lowhangingfruit.dev/2019-10-21/automount-nfs-on-macos/ , no luck. Anyone can help me? Thanks!
