Any control of MapKit font sizes?

I understand that MapKit automatically sizes the font based on the system Dynamic Type size.

The thing is, the default font size is plenty legible for me system wide except for some type in MapKit, while other type in MapKit is already plenty big.

For instance, the stream names are much harder to read than they should be by default. And if I increase the system Dynamic Type size, then it makes some MapKit text much larger than needed, while the stream text can still be hard to read.

So is there anyway to override or adjust font sizes in MapKit? I'd like to be able to apply percentages to Dynamic Type suggestions. Like for streams, I'd like to scale it somewhere between 133% and 150%.

The smallest Dynamic Type is size is .caption2 at 11 points with default settings. With default Dynamic Type settings, it looks like MapKit is drawing stream text around 7 points.
