“Saturday Night Live” cast members won’t be forced to appear alongside controversial billionaire Elon Musk when he hosts the show, Page Six is told.

“Speaking historically, if a cast member has been that unhappy, they don’t have to do it,” a source told us.

The Tesla founder, 49, is set to helm the NBC institution on May 8 — but some cast members have made it clear that they’re less than enthused by the prospect of having him on stage at Studio 8H.

After Musk tweeted, “Let’s find out just how live Saturday Night Live really is,” cast member Bowen Yang wrote: “What the f–k does this even mean?”.

As for Michael Che, the “Weekend Update” host, 37, joked to Jimmy Fallon this week that he hopes the billionaire will uphold the “SNL” tradition of hosts giving “a couple million dollars” to each cast member.

Musk will join the cast for rehearsals at 30 Rock beginning on Tuesday
