Hi,
Let say we have a layer with some lines, it can be pen or brush or something else ; that does no matter, I can take any of them for the following purpose : I would like to change the thickness of an already drown line through someting like options, preferences, etc.
Is it please possible ?
Best regards.

Not with just options. Two ways:
1)
Filters ➤ Generic ➤ Erode (yes, assuming black over white background) after possibly making a selection around said lines (plus some space to include the pixels that will be covered by the thickness increase)
2) Color select the line (perhaps with an intersection with a selection around the lines of interest, to not select the rest of the image (see
here for techniques to do so)) then
Select ➤ Grow to enlarge the selection and bucket-fill the selection.
You can try
Filters > Distorts > Value Propagate...
If you are on a transparent layer select "More opaque" to increase and "More transparent" to decrease

As you can see on the screenshot you have many option (More white/More black/colors and so...)
This will increase or decrease by 1 pixel (once you clicked OK, just do Ctrl+F to repeat until you are satisfied with the thickness)
If things start to look funky, un-check the different check boxes
