Hi pipixia_8_8

Yes, you can read the MAC address directly be reading NRF_FICR->DEVICEADDR[0] and NRF_FICR->DEVICEADDR[1] registers

These registers are 4byte in size. MAC address is 6byte in size, DEVICEADDR[0] contains the least significant bits of the device address (4bytes) while the DEVICEADDR[1] the rest of the two bytes (most significant bytes)

Hope that helps
