Not clear how to solve. Function seems to just print to stderr. suppressWarnings and suppressMessages do not solve the problem.

Code snipped to work on:

library(ggplot2)
data.frame(
  x=rnorm(20),
  y=rnorm(20)
) %>% ggplot(aes(x=x,y=y)) + geom_point() + suppressWarnings(geom_smooth( method = "lm", se=F, color = "black"))

Update: Can we avoided by explicitly specifying the formula.

library(ggplot2)
data.frame(
  x=rnorm(20),
  y=rnorm(20)
) %>% ggplot(aes(x=x,y=y)) + geom_point() + geom_smooth(formula = y~x, method = "lm", se=F, color = "black")
