In the documentation, it is said under 'MeshDensity' option of 'fplot':

"Number of evaluation points, specified as a number. The default is 23. Because fplot uses adaptive evaluation, the actual number of evaluation points is greater."

This is not suitable for my work to not be able to have a fixed number of evaluation points from a plot to another.

So, is it possible to set an exact fixed number of evaluation points?

‘So, is it possible to set an exact fixed number of evaluation points?’

Likely not with fplot. Since fplot plots single-variable equations, a more appropriate option would likely be to use linspace (or logspace) to create the independent variable, and then plot your independent and dependent variables.
