Like any of our other BLE Chips / Modules, the CYBLE-022001-00 module can also act as a Master.
In the below list of example projects, you can refer Project 6 and Project 11 to implement a Central:
Also, in Project 20 in which a UART BLE Bridge is demonstrated. It has two projects, one for the central device and another for the peripheral device. You need two CYBLE-022001 devices for trying out this, one as central, one as peripheral.
