Avoiding texture repetition on big walls?

How to avoid texture repetition on big walls?
I am exporting the texture from Substance Designer in my case.

Is there any randomization method you can do in Materials in Maya do so such thing?

Any ideas much appreciated.

1. macro (low frequency)  texture layer with add/sub blending  + decals  (could hide this to certain extent)

2. bigger texture/texel size  with more unique cover.  it shouldn't be down to every microbe  on surface.

3. non-square textures and stretched texel size  to make bigger cover in most visually repeating direction. ( counter-weighted by  squeezing in the texture)

4. alternate / shifted/ mirrored  insertions

5. UV shifting  shader  ( perfectly ok for such subject with natural "seams")

6. two materials  mix shader + vertex color mask

7. combination of all above

Also  this repeating darker brick  is what makes most of an issue.    You  should train  certain   sense  of a balance  and  counter weight something visually  prominent  in other  quadrants of a texture . 

It's not always possible In Substance Designer   and sometimes requires manual re-shuffling .   But checking tillable preview for each pattern and trying different seeds  helps .

Also  Hipass/freqencies separation is sometimes a quick solution but beware of typical halo issues  hipass creates . It's just a blur under a hood. Too much of it could  totally destroy the nature impression.

So in the end it's a bit of an artist balance sense and taste.  Similar to music where you mix low frequency basses , hi pitch  sounds and main melody  intertwining each other into something looking unique.

Thank you so much.
Do you have any link to a video showing parts of what you mentioned?

I have much much better results now... Thank you again.
