Is it possible to give the compass an upward direction only? Such as north up, direction up, etc.

Yes in the compass menu -> options -> rotate the map (with compass)

I mean when I follow a route the compass direction is set "direction up GPS".

I'm sorry I don't understand what you mean...

When I follow a route and I have started the compass, the map should not rotate constantly at the slightest movement, but for example there is a straight street and the direction of the map is forward. A turn follows and the map turns and straightens and the direction is up again. And so with each spin. The direction is always forward and does not rotate constantly but turns in and stops until the next turn.

So use the "map rotation with GPS" option in the Location menu, and not the map rotation with compass, which is much more noisy.
If you want your direction always up, then the map must rotate accordingly.
