Ok, this is already implemented, just not well-documented.

According to the docs:
router.navigateByUrl(url: string, _skipLocationChange?: boolean) : Promise

Has a parameter _skipLocationChange that will not modify the history.
These will do the trick:

router.navigateByUrl('/404', true); router.navigateByInstruction(router.generate(['/404']), true);
