yes. You have to work hard to get into an academic IM residency that sets you up well for this. But it’s realistic level work.
Get 50th percentile steps, do well on sub-Is and get good letters of rec +\- a little research. As long as you can do this and aren’t picky geographically, it’s fine.
SDN acts like getting into a university IM is a tall to nigh-impossible feat for DOs. And it’s certainly ridiculous for top programs and the most desirable locations. But just any academic IM program (or large community program with similar opportunities) is honestly not that big of a deal. The DOs who can’t do it are typically the ones who struggled academically and would have had problems at an MD school too and/or just restricted themselves to a handful of big cities.
