help get this dns menu back

[oliver555]

hi, i set up my vps and went through the setup and when it asked (what dns do you want to use with thevpn) i selected the third option (3) but i want to get this menu back up because i want to select option 1 instead of option 3 what would be the command to get this menu back up without going through the whole process again heres a screen shot of the menu i want to get up http://prntscr.com/e7hzh0

You can either re-run the script or you can edit the server.conf file in /etc/openvpn
