Is it possible for miner who refuse to accept ETH2.0 to fork the current chain & delay the difficulty bomb to 2121?

Hi guys,

I am thinking about a kind of approaching risk, where large amount of Ethereum miners who refuse to upgrade to ETH2.0, and decide to fork the current ETH chain and delay the difficulty bomb.

Is that possible?

Can miner fork the current ETH chain and then delay the difficulty bomb?

If this happened, how will that effect the value of Ethereum?
