I mean, you're only tickling power limit, you're not seeing a hard green bar or anything, so that's not really that bad.
You should be able to push way higher than +25 though. Keep in mind, the Ampere cards (I think all of them) go in +15 increments, so you're either running +15 or +30 actually... from the fact that your clock is showing 2085, that's +30 - since default boost clocks are in the 2025-2055 range depending on temperature under load.
I'd say go straight for the gut if I were you, if you want power efficiency & unlikely to hit power limit, 2100MHz @ 1025mV should be stable, I'd be shocked if it's not... that's a +60 effective clock, with lower than stock voltage, should result in lower temps as well as less power draw.
Or you can go bonkers & try to do what I'm running for funsies, 2160MHz @ 1068mV, with a +1000 memory overclock. No clue if that's something most cards can do, I have a feeling it's not, especially the 2160MHz @ 1068mV part - that's basically a +120 offset, with the second lowest stepping of stock voltage (1062mV-1100mV). For me, that still runs cooler than stock, while giving better FPS, and still drawing less power (most of the time).
Trying to push raw clocks probably isn't going to get much, or maybe not any, further that going for a more optimized overclock/undervolt. Just my opinion. I haven't really messed with voltages in Classified Tool either - I'm unsure of what voltages are and aren't "safe" for 24/7 slash full-time usage, so I haven't bothered with it at all outside of the one time I messed with another BIOS.
For reference, this is what I saw when running the 2160/+1000 settings, in a pressure run of Cyberpunk 2077 with all the settings maxed, including RT stuff being fully on with the last setting on "Psycho":
The voltage says 1.094v because I had to reset to stock for a moment when the core was boosting to 2175MHz because I didn't want that to cause a crash.
Screenshot at my resolution with those settings, the game can definitely bring the 3090 Kingpin even at those clocks to it's knees:
