Discussion: methods for removing contaminants and cross-talk

I have a case where my sequencing facility sequenced negative controls that showed bands/PCR products in the gel. I gather from reading this thread, this is not a case of cross-talk or index hopping type of contamination and that just removing the features that appear in the negative controls should fix the problem, correct? I realize this thread is from January 2019, almost two. years ago. Has decontamination been added to the current version of Qiime2?
thank you
