Berntd, since you have Biab 2019 you do that in the Mixer. Go to the Help File Index and type in Mixer. That gives you everything you need to know about how the Mixer works. Scroll down in that window until you come to the Plugins section. Read that part but I'll give you the instructions.

You click on the Plugins tab on the top of the Mixer window to start. You see each track. Piano should be Track 2, click the little down arrow to the far right of that track and it opens up the Plugins window. The first slot is for midi instruments and the next three slots are for effects. Click on the down arrow in the first slot and you will see all the synths you have. You should be able to select your Yamaha driver. Then select a different synth for the rest of your midi instruments.

This is something new for Biab. I'm not sure if it started with 2019 or 2018 but prior to that Biab only had one midi output port so you could not do this.
