TRF7970A: Unshielded inductor usage?

Part Number: TRF7970A

Looking at the NFC Transceiver Reference Design: https://www.ti.com/tool/TIDM-NFC-TRANSCEIVER

The inductors in the matching circuit at the output of the IC use unshielded inductors.

Is there a requirement to use shielding between the circuit and the antenna?
