No. The switch to POS is entirely a socially initiated hard fork being built by Eth holders, users and developers. The miners who don't want to play along are effectively being fired. And there is a lot of economic incentive to get that fork done - mining is a really expensive way to generate consensus on a blockchain. What miners earn via block rewards is coming out of the pockets of other eth holders because of the coin's inflation. Ethereum will be able to reduce it's issuance/inflation by roughly 10x in the switch. The starting point was launching the beacon chain back in December 2020, a separate chain designed to provide consensus and validation of mainnet ethereum in the (hopefully near) future, whose validating participants fund their deposits through what is just a normal contract on mainnet ethereum. From there that beacon chain has been refined and built into a protocol with multiple implementations, and had its stability monitored and tested. From here, it's just a matter of forking mainnet ethereum into using the beacon chain as its consensus provider and ignoring the miners. And that step is pretty deep into the final testing phases using ethereum's long running testnets to run through the 'merge' at it is called.
