Block read is similar:

We need to imitate that call with blockNo 0 to set a uid.

mfCSetUID provides example logic for UID set workflow:
-Read block0 from card in field with MifareCGetBlock()
-Configure new values without replacing reserved bytes
memcpy(block0, uid, 4); // Copy UID bytes from byte array
// Mifare UID BCC
block0[4] = block0[0]^block0[1]^block0[2]^block0[3]; // BCC on byte 5
Bytes 5-7 are reserved SAK and ATQA for mifare classic
-Use mfCSetBlock(0, block0, oldUID, wantWipe, CSETBLOCK_SINGLE_OPER) to write it
