Hello, I am new to all of this and just purchased a Puli AX - XE3000NR. I have already updated the firmware to its latest manually. I am trying to update the plugins to the latest firmware for example AdGuardHome. I checked its firmware at the bottom of its page and its 107.26 but doesn't give me an option to update it through the GUI. I do see that Github page has the latest firmware of 107.52 and I'm assuming I have to update manually but I have no clue as to how to start that process or which file i need to actually download. I have tried looking for other posts and couldn't find anything useful for me to even start it. I also tried searching videos and no luck from there either. I do have SSH running and able to access the router through that but again I am no expert on it and basically a novice when it comes to it. I would really appreciate if someone could give me some insight on how to even start process. Let me know if I missed anything.
Well, well 
Not gonna lie I did see this particular post but you did mentioned a disclaimer on it and being that I just got this device I was afraid to mess it up without going through proper channels. I never actually messed with scripts so i am unfamiliar of trying it out without making a mistake.
It is way more safe to try my script than trying to do it manually 
Give it a try, the feedback is great so far.
I'm assuming I have to have some form of internet going through the box to get the update. Is there a manual way to do this?
You definitely need internet, yes.
You want to manual?
There go Adguard Home Upgrade - #6 by slesar
I recommend @admon 's script for auto update Adguard home. It is pretty easy.
However, is your own risk to update adguard home and not much difference version. Even working fine old version.
Well I bit the bullet and went for what you said and it updated with no issues so far. Guess I will need to keep an eye for something to happen but hopefully not. Thank you for this.
