For those who want to apply this change permanently (i.e will apply when knitting the document), I made a fork with the code change.
remove.packages("enrichplot")
invisible(lapply(paste0('package:', names(sessionInfo()$otherPkgs)), detach, character.only=TRUE, unload=TRUE)) # unload all packages
devtools::install_github("BarryDigby/enrichplot")
Thanks @lianchee11 for the code.
* The pathway description in green font will be omitted from the plot.
