Spark plug Mainentance change

Can someone enlighten me or point me in the right direction for preventative maintenance? I’m wondering when they recommend to replace the spark plugs and or does my computer tell me to do it?
I’m finding manuals online but not specific to AWD model and I know that’s important when I’m ready to do fluid changes etc I’m assuming

I changed mine on my 400 and 430 every 100,000 but if you are skeptical, you can always do every 6yrs or 60,000 miles.

You can buy Toyota's TIS subscription for two days for $20 or so (https://techinfo.toyota.com) and download all the manuals and diagrams you need. I used it this way couple of times in the past. You can also find part numbers on the parts.lexus.com, or just call parts department of your local Lexus dealer.
