How to lower the negative effect of not having your current fief close by, when the game is looking for candidates to receive a conquered fief.

I found the code, but I'm new to coding and am not sure what should be changed by the Distance Factor Equation.

Image and the pasted algorithm are different. Probably mexxico added some pro-player factors after the discussion at the link.
num7 (distance factor) is a direct multiplier in the final formula so you should narrow down its possible values to diminish its effects.
Decreasing the Math.Pow constant 0.5 helps.

float num7 = (float)Math.Pow((double)(num6 / Math.Max(val, Math.Min(400f, val2))), 0.5);

Things get interesting after this.
The distance value is clamped between 2 values in those Math.Min and Math.Max functions.
Campaign.AverageDistanceBetweenTwoTowns * 1.5 * 0.25 <= distance <= 400
You can either increase 0.25 or decrease 400 or do both.

float val = num6 * 0.25f;
.
.
.
float num7 = (float)Math.Pow((double)(num6 / Math.Max(val, Math.Min(400f, val2))), 0.5);

But be careful, if two limits of that clamping becomes same, lower limit exceeds the upper or upper limit becomes smaller than the lower one, distance factor is no more a factor.
I advise you to decrease the Math.Pow constant. It's neater.
For 16 and 256:
0.5 creates 4 and 16 (x4 times)
0.25 creates 2 and 4 (x2 times)
It got narrower as you can see.
Edit: Second way narrows down the factor but not in a nice way. It simply ignores some values near the limits. Just change the constant 0.5
