I have to suspect that you are wrong. Can you provide a source? There is no mentioning of difficulty in the spec, instead there are predefined slot times:

https://github.com/ethereum/eth2.0-specs/blob/dev/specs/phas...

Here is how they sync: https://ieeexplore.ieee.org/document/8946264

Assuming they describe the BeaconBlocks mentioned here: https://github.com/ethereum/eth2.0-specs/blob/dev/specs/phas...

Also, which effect would an increased difficulty have?
