How can I create constants in Desmos which users cannot change with a slider?

Question

I want to define a constant to use in a Desmos graph, but when I try to do this by creating an expression, Desmos allows users to change the value of that constant with a handy slider, e.g.,

Desmos suggested doing that by using a ratio of inbuilt constants, but this seems to obfuscate the intention. Is there a more straightforward way I can keep constants constant in Desmos?

Apologies that this is out of scope. I saw other [desmos] tagged questions and thought it might be appropriate because this site welcomes questions about "Software that mathematicians use" — David Lovell, May 05 '22 at 04:59

One way to do this is to create a helper function $$ C_{onstant}(x) = x $$ and then use it to assign values to your constants like this: $$ c=C_{onstant}\left(299792458\right) $$ which eliminates the slider in Desmos

Another way is to restrict the domain of $c$ as such:

This way the slider becomes unusable:
