Deactivated plugins after following guide exactly. Should I enable them?

[Ricardo4444]

I just followed the STEP guide for Skyrim LE and finished installing everything. It seems I have a working install!
However, some .esp plugins seem to be disabled by default. Just wanted to double check if having them checked/unchecked will lead to issues, or if I can just choose to use them. the following plugins seem to be unticked by default:
- AbandonedPrisonNavFix.esp
- MCMHelper.esp
- RUSTIC SOULGEMS - Sorted - ESL - GIST.esp
- WACCF_Armor and Clothing Extension_SPID.esp
- UDHAP - en0.esp (and all other numbers up to 4)
Should I enable this plugins? They all seem like useful fixes. Are they included in the compatibility patches?
Thanks in advance to anyone willing to help!
