I have single cell RNA-seq data (10X genomics) data from PBMC and trying to do differential gene expression analysis comparing different conditions (not comparing different clusters or cell types) per cell type. I am trying to use Seurat R package but I think it only compares clusters to detect markers. using Seurat, is there any way to perform differential gene expression analysis comparing different conditions per cell type? if not, what R package can do this analysis?

You need to perform pseudobulk method for the differential expression that you are planning. Please check out the following methods.
