The colour scale for edges is called edge_colour. Can I get you to test whether guides(edge_colour = FALSE) works
from ggraph.

"Me too". Was about to file this as well, here's my example in case it's helpful:
library(ggraph)
library(igraph)
hairball <- graph_from_data_frame(highschool)
E(hairball)$year <- as.character(E(hairball)$year)
## cannot turn of the colour guide
ggraph(hairball, layout = 'kk') +
geom_edge_link(aes(colour = year)) + guides(colour = FALSE)
I ran into this because I have a lot of edges I want to illustrate colours for, I will convert the values to a continuous scale for now.
Thanks!

Oops, it does work:
library(ggraph)
library(igraph)
hairball <- graph_from_data_frame(highschool)
E(hairball)$year <- as.character(E(hairball)$year)
## edge_colour guide
ggraph(hairball, layout = 'kk') +
geom_edge_link(aes(edge_colour = year)) + guides(edge_colour = FALSE)from ggraph.
