To expand on what he said - there is NO remote that can connect to another device thru RF, unless it was made to do so for that device.
There are of course a few exceptions to this rule that have been seen over the years. But it is rare and only involved 1 or 2 other devices.

The 2017 edition of the Shield has NO way to control it with IR from the factory. You have to purchase a separate 'USB to IR' dongle to plug into the Shield, in order to control it with IR.

What you then need is either the URC MRF-260 or MRF-350 RF base station. The MX-900 connects RF to the base station, then an IR emitter connects from the base station to the Shield's 'USB to IR' dongle.
Or you can get an inexpensive IR repeater and use that instead of the URC base station.
