How does BLE5.0 use DTM to perform 2Mbit fixed frequency test, because authentication needs, I have no idea how DTM sets this BLE5

For RED CE certification, the rf test data of bluetooth 5.0 is required

How "rf test data for CE certification" link to "DTM to perform fixed frequency test because authentication needs"? If you need to perform fixed frequency constant career tests then there are other examples in nRF5 SDK, this is not part of BT SIG DTM specification.

The DTM example in the SDK should be able to support 2Mbit mode. Have a look here.

The DTM firmware is made to work with the dedicated test equipment (such as the Anritsu MT8852 or similar).

If you want to manually control the radio, it's easier to use the radio_test firmware. Data rate can be chosen by pressing "m".
