QSFP28 Ports on N9k - Can they run at 1Gbit?

[j.a.m.e.s]

I temporarily need to connect a 1Gbit fibre on one of the QSFP28 ports (49-54) on a 93180YC-FX  using a GLC-SX-MMD. 

Is it possible for these 40/100G ports to scale down to 1G with a QSA adapter (CVR-QSFP-SFP10G)?

According to the Transceiver Matrix, the answer is yes, but I just wanted to check.

The uplink can support up to six 40- and 100-Gbps ports, or a combination of 1-, 10-, 25-, 40, 50-, and 100-Gbps connectivity, offering flexible migration options.

High level with this convert it should work :

CVR-QSFP-SFP10G 

Note if you looking Copper  : Only 1Gbps speed with GLC-T & GLC-TE is supported with CVR-QSFP-SFP10G adaptor.
