There's a fix for Lego Star Wars: The Skywalker Saga insisting on a 60 fps cap

pcgamer.com:

Thanks to PCGamesN, we now have a fix for one of Lego Star Wars: The Skywalker Saga's few graphical hiccups: its stubborn insistence on defaulting to a 60 fps cap on launching the game or Alt+Tabbing out, no matter what you set in the in-game menus.

To ensure your preferred framerate cap won't just switch when you're not looking, follow these steps:

With those steps accomplished, the game should launch with and maintain your desired framerate cap. PCGamesN's primary concern was the game resetting back to 60fps on Alt+Tab, but I found this fix also addressed my issue of the game defaulting to 60 fps on launch, requiring an adjustment in the options menu every time I wanted to play.

Perhaps it's not the greatest hardship a human being could face, having to tweak a few menu options to go beyond 60 fps. After all, our distant ancestors had to contend with 720p 30 fps in Dark Souls: Prepare to Die Edition back in the Before Times. Still, if you're one of the elect brandishing a high-refresh rate monitor, you're gonna want every one of those precious frames. I know I do.
