remove custom-set-*

[Anast Gramm]

Hey list,

I have disabled the customs file since I want to have my configuration
in one neatly organised org file.

  custom-file (make-temp-file "")

I want to remove custom-set-faces from the code below, but I don't know how.
setq doesn't work, and I don't know what to try.

  (custom-set-faces
   '(company-preview
     ((t (:foreground "darkgray" :underline t))))
   '(company-preview-common
     ((t (:inherit company-preview))))
   '(company-tooltip
     ((t (:background "gray4" :foreground "gray85"))))
   '(company-tooltip-selection 
     ((t (:background "dark olive green" :foreground "gray100"))))
   '(company-tooltip-annotation
     ((t (:background "gray4" :foreground "goldenrod1"))))   
   '(company-tooltip-annotation-selection
     ((t (:background "dark olive green" :foreground "goldenrod1"))))
   '(company-tooltip-common
     ((t (:background "gray4" :foreground "gray42"))))
   '(company-tooltip-common-selection
     ((t (:background "dark olive green" :foreground "gray69")))))

Also from here, how do I remove the custom-set-variables

  (custom-set-variables
   '(TeX-view-program-selection
     (quote
      (((output-dvi has-no-display-manager)
        "dvi2tty")
       ((output-dvi style-pstricks)
        "dvips and gv")
       (output-dvi "xdvi")
       (output-pdf "Zathura")
       (output-html "xdg-open")))))
