Facet, plot axis on all outsides

Is there a way to mirror the x-/y-axis to the opposite side (only outside, no axis on the inside)? My goal is to get something like:

enter image description here

MWE

library(ggplot2)

ggplot(data = iris, aes(x=Sepal.Length, y=Sepal.Width)) +
  geom_point() +
  facet_grid(rows = "Species")

This should work:

ggplot(data = iris, aes(x=Sepal.Length, y=Sepal.Width)) +
  geom_point() +
  scale_y_continuous(sec.axis = sec_axis(~.*1))+
  scale_x_continuous(sec.axis = sec_axis(~.*1))+
  facet_grid(rows = "Species")

enter image description here

Yes, you can use the guides() function to set axes for secondary positions as well, see example below. To have it more like your example, the strip placement should be changed to "outside".

library(ggplot2)

ggplot(iris, aes(Sepal.Length, Sepal.Width)) +
  geom_point() +
  facet_grid(rows = vars(Species)) +
  guides(
    x.sec = "axis", y.sec = "axis"
  ) +
  theme(strip.placement = "outside")
