Tatwi: You can, however you will need to manually manage your saved game folder to prevent the various versions from using the same folder.
C:\Users\[YOURUSERNAME]\AppData\Roaming\HelloGames\NMS\DefaultUser
DefaultUser is the folder for the GoG saved games. Make a copy of that and rename the copy. For instance, I have DefaultUser_177 for my 1.77 install. When I want to play 1.77, I rename my DefaultUser folder to DefaultUser_current and then rename DefaultUser_177 to just DefaultUser and then I launch the 1.77 version of the game from its folder (which I copied to a different directory before upgrading to 2.0).
