Shorter interval than 1 (2) seconds for hyperlapse on Mavic 2Pro

Hi there.
I’m making timelapses of traffic and I really need shorter interval than 1 second.
I’d need something like 1/4 second or 1/2 second interval. Otherwise the cars jump too much even with longer shutter speeds.
This may be limited by DJI hardware or the time it takes the hardware to write to cache/card. Don’t really know
I somehow got the impression that Litchi had shorter duration but it doesn’t. 2 second interval on Mavic 2 pro.
Anyone know how to get around this?
Best regards
