More decimal on lcd display for step

Hello everyone,
I'm a beginner on Marlin firmware,
I finally received my skr e3 motherboard on an ender 3,an I have a problem to the step.
I can enter the steps / mm only at one digits (80,x) before on the last fw I had two digits after the decimal point(80,xx) , or it must be reconfigured to have availability on the screen?
I want to configure the step on the screen.
My pc is not near to my ENDER3, I don't have an octoprint.
Thanks!
Sorry for my bad english... I am french
