I am not going to straight up say you can disable the archive command as 
I will not be the one that has to bear the consequences.

What I will say:

1) Have you tested that the Barman, repmgr setups work to do a recovery?

2) Are the two archive processes(streaming replication, 
barman-wal-archive) going to different locations?

3) There is also the question of whether the two archive methods are in 
sync. In other words would you get the same restore if used either at 
some point in time?

My personal opinion is you would be best served by having only one 
tested process working.
