Is there a way to change the arrow types of a variable PCA plot using R?

Question

I am using the factoextra package to plot a PCA and I have my variables and I coloured them by their contribution. However half of them are Temperature related and the other half are Precipitation, is there a way to manually make half of them with a dashed arrow line to distinguish them? (all the variables are active ones)

My data:

#PCA
res.pca <- prcomp(bioclim, scale = TRUE)
var.p <- fviz_pca_var(res.pca, col.var = "contrib", gradient.cols = c("#00AFBB", "#E7B800", "#FC4E07"),repel = TRUE)

I also tried using a ggplot variant where the geom argument lets you change the arrows to points and show text but I am unable to make their lines dashed. Does anybody have a clue how to manually choose some variables and make their lines dashed? Or is this not possible at all?

ggpubr::ggpar(var.p, xlab= "PC1 (0.56)", ylab= "PC2 (0.18)", legend.title = "contribution", legend.position= "top", geom= c("arrow","point", "text"))
