Mahalanobis Distance in DBSCAN Clustering with R

Question

I have read the R documentation and some sources. As I understand it, the DBSCAN syntax in R automatically uses the Euclidean distance. For example like the following syntax:

kNNdist(data, k = 3)

kNNdistplot(data, k = 3)

abline(v = 21)

abline(h = 2.079)

dbscan(data, eps = 2.079, MinPts = 3)

What if I want to use Mahalanobis distance? Is it possible?
