Kinda, but I'm not fully sure. But here's a half-valid answer:

If all you want to do is manually trace low-levels of DOS calls themselves, you can do that via a "resident" debugger (386SWAT, DeGlucker, Insight) or similar (BOCHS? DOSEMU?). Logging to file may?? be possible via DOSEMU or FreeDOS debug kernel, but I'm even less sure as I've never tried.

There are other external utils (usually TSRs) that log "some" interrupts, but I'm not sure how much, many, whether they report register values (doubtful), full filenames (or LFNs), etc. Don't get your hopes up, most are old and incomplete (but better than nothing). The only one I've truly used more than once is KGB, and it's woefully incomplete (but good for simple fopen/fread/fclose/exec curiosity).

Argus, KGB, TRACE, UI21DEB.

There might be more (most likely), but I dunno offhand.
