How can the reads be assemble to unitigs with ONLY EXACT sequence overlaps?

Question

[BioGeek]

I'm now working on a metagenome assembly project. There, I want to segregate and assemble all of the reads with stringent parameters: they should not overlap segments even if they have a single mutation in the sequence. Is there any software/tools or flags that can assist me in accomplishing this...

Note: At the moment I don't care about N50.

Not 100% sure, but probably unitigs of BCALM are what you need (https://github.com/GATB/bcalm)
