Description
I am using check_model() for a course, and it's a wonderful teaching tool. However, sometimes the confidence interval bands generated from the LOESS fit from geom_smooth() are ridiculously large, thereby expanding axes and making any potential pattern in the residuals unnoticeable. Is there a quick and easy way to turn off CIs so the y-axis behaves? I wasn't able to a discover a quick fix to this besides extracting components from check_model() and replotting with geom_smooth(se=F) or forcing it linear with geom_smooth(method="lm").

Research direction
Start at the check_model() entry point and trace how its geom_smooth() LOESS plot is assembled. The requested result is a way to disable confidence-interval bands without extracting components and replotting; verify the behavior with the provided lm(libido ~ dose, data=df) reprex.
