Try to install DEDS if (!requireNamespace("BiocManager", quietly = TRUE)) install.packages("BiocManager")

BiocManager::install("DEDS")

Get this message: Installing package(s) 'DEDS' Warning message: package ‘DEDS’ is not available (for R version 4.0.1)

Is there any other way to download it?

Thank you!!

Seems to be deprecated. And not building besides. If you want to revert to R-3.6.1 and Bioc 3.10, you can get it though:

But you know, the usual caveats about lack of support and it's being deprecated so how well was the upkeep and all that apply.
