It's possible, but shouldn't be necessary. Can you provide a
reproducible example which shows why you need this?

Not in those terms, but you can explicitly specify labels as

scales = list(x = list(at = c(1, 2, 3), labels = c("a", "", "c")))

Again, not in those terms, but you can fake it using

key = list(text = list(c("loess", "points")),
           lines = list(lwd = 2.5, col = c("gray", "blue"),
                        cex = 1.25, pch = 19,
                         type = c("p", "l")))
