No. And I don't think any US state would seriously contemplate secession today however polarized politics are. That said, if any state or group of states did overwhelmingly want to breakaway from the US, it seems unlikely that there would be meaningful support for the federal government to go to war to stop them.
There have been the Calexit movement [1] and various movements in Texas [2]. Texas in particular has some substantial poll numbers. Given that states rights are far less than they were in the 19th century, I expect the US government to be even more likely to prevent succession in the infinitesimal chance it would happen.

Your point about the erosion of states rights is certainly fair. In any case, it's hard to say what "prevent secession" means without the context of the circumstances.
