While both can coexist without conflict, you can reduce the clutter on your SD card as you don't really need two things doing the same thing at the same time.
To remove sigpatches, remove pretty much everything that's usually included in sigpatches archive file i.e.:
- folders es_patches and nfim_ctest from the atmosphere/exefs_patche folder.
- folders fs_patches and loader_patches from the atmosphere/kip_patches folder.
- patches.ini file from the bootloader folder.
Also, remove kip1patch=nosigchk line from the hekate_ipl.ini file.
That should be it. Don't forget to reboot afterwards.
