Is there anyway to make FDR separately


I want to perform DEG of miRNAs and i just did it with Deseq2, But i need FDR for Volcano plot, and since i used salmon for quantification, i think edgeR not going to get me any results, So is there any other way to do that ? i know if i use featureCount i can do DEG with EdgeR, But that way has some other kind of problems.
