I have a Grizl. Since I mostly ride on concrete (unfortunately), I got a secondhand wheelset so I could ride on optimized rubber during the week, then quickly/simply swap for the weekend adventure.
I bought an identical cassette for it. However, while the gravel set shifts perfectly (it was adjusted well from the factory), the road set is a bit rough especially lower in the range. It has even jumped a gear when I’m pulling hard going uphill.
Is there something I can do to adjust this quickly for the second wheelset? Some spacer or something for the cassette maybe?

Likely not. The best course of action is to be sure you are using the same hub and cassette; that will eliminate most issues with slight spacing discrepancies (assuming there isn’t abnormal wear on either cassette or the chain). If you know how to adjust the rear derailleur just remember how many clicks you turn the adjuster knob and in which direction to make the road wheelset work.
I have two identical sets of high quality wheels for my bike and despite being identical, they never quite swap out perfectly. I have come to accept that I will have to adjust the derailleur barrel just a little bit every time.
You can eliminate the problem by buying two wheel sets with hubs from the same manufacturer (at least that works with DT Swiss hubs).
The cheap (but tedious) solution is to adjust the position of the cassette with very slim spacers. Unfortunatly, I don’t know of any spacers for shimano hyperglide that go below 1mm thickness. If you have access to a 3D printer, I would try to print them.
I have two wheel sets, different hubs and they both shift perfectly.
This is a perfect time to learn how your shifting works. Find a video online and learn how to index your derailleur. Do it repeatedly until you know what your doing. Then try to get it setup so it works on both. It may not be perfectly adjusted on the gravel even though it’s shifting fine and there is enough of a difference in hub sizing to make it show up on the second set.
There are spacers for cassettes, make sure both wheels have them if necessary.
And as others have said you may find a number of clicks on the adjuster that makes it work.
I have two wheelsets and my hubs and cassette are 99% the same, but the rotors are slightly off, so while my shifting is (almost) perfect between the two, I need to adjust my back brake about 0.5mm otherwise I get brake rub. So close, so far away.
