By avoiding complex relations with Next Gen, DS9 and Voyager if it’s set to close to the latest ST timeline, and by avoiding referencing Enterprise and trying to preqelise TOS, which is where they’re at. Just look at the holy mess SW got into with eps 1-3.
Plus we can have a shitload of new technology too. Enterprise was so embarrassingly ahead of TNG, let alone TOS. Let imaginations run wild.
