I don't think, just an acronym, but my impression is that the only thing BRICS or BRICS+ agree on and are actively co-operating to achieve is collectively getting off the dollar and ending the effects of the so-called exorbitant privilege on themselves.
Either one gets rid of the oil trade-- which I think is quite feasible, then the need to acquire dollars to buy these products goes away, so there's nothing more needed, or one negotiates something with one of the many countries which either have or could acquire the ability to produce oil where one bypasses the dollar trade.
Maybe, if they didn't have Russia in the group and had talked to more people about the sanctions, something like 'we need this, and the alternative is Russia-- can't you be flexible and not sanction Venezuela', they could have even used Venezuela.
