Yes sir, there is. The “Separate views” you mention Dorico calls parts. You can create as many parts, with whatever combination of instruments you want from the same main score.
In Setup, for each part, there is the option to display tab, notation, or both for fretted instruments, including for which tuning. So you can choose to show tab or not in the main score, tab or not in the guitar part, etc.
Dorico creates the tab automatically from the notation if that is how you want to work. It will let you write/edit ether stave and the changes will be made in the other.
