11 speed road cassettes for 10 speed hubs?

Hi, 
I know about the shimano 11-34 offering. Are there any others out there? 

I’ve thought about having the SRAM 11-36 cassette machined to fit...

What makes you think you need to modify the SRAM cassette?

I had just this mod done by https://www.lascoconcept.com/en/11s-cassette/  Had to buy the cassette and send it to them because they don't offer that specific one but it went fine.

The SRAM 11-36 is made to fit 11 speed road freehubs, it won't fit a 10 speed freehub or a 10/11 speed mtb freehub.

Same cassette? 

You can look at Sunrace cassettes.  When I built my multi-surface bike I knew I needed something  really low and wanted to try 11 speed so the jumps would not be massive and bought their 11-42.  Paired with a 46x30 it covers about 95 percent of my needs.  (I just wish the 11-cog had never become a thing.  It is not that useful and the jump from 11-13 makes really clunky.)   I am using a Shimano XT 10 speed hub.

SRAM 1170, 11-36, yep!

I bought a Sunrace 11-32 that was supposed to fit on a 10 speed freehub, but it didn't fit on my Mavic Crossmax 10 speed freehub.  It even came with a spacer to use on 11 speed freehubs.  

Here's a picture of the machining they did.
 

In addition to the Shimano 11-34 you mentioned, they also make an 11 speed 11-40 and 11-42 that fit a 10 speed hub. Sunrace also makes an 11 speed 11-40 and 11-42 and 11-46 that all fit a 10 speed hub. I'm not aware of any 11 speed 11-36 cassettes made that fit a 10 speed hub.

I can vouch for the 11 speed Shimano 11-40, Sunrace 11-40 and Sunrace 11-42 all working great on 10 speed hubs.

I know about the larger mtn cassettes, and currently run a 38 up front with an 11-40 out back. I’m toying with GRX 2x on my new build, though. I was thinking 30/46 with the 11-36 cassette out back might be nice. I think I’d appreciate the tighter gear spread, yet bigger range. I like the simplicity of 1x though...

I think you’re all going to far. The machining option is beautiful, but pretty costly.

 Just take out one of the middle cogs and run the 11sp cassette with only 10 gears.

I played around quite a bit trying to do something along those lines.  It's hard to take a cog out of a modern cassette!  Many of the larger cogs are built on alloy "spiders," and can't be individually removed.  The gear jumps in these cassettes are already so big that taking one out in the middle will put a huge gap in the spacing.  (not to mention potentially make shifting clunkier.)  Also, I knew from other bikes I'd had the 11-36 was a nearly ideal range for me with 34/36-46 cranks it was practically perfect.  So I ponied up for what I really wanted.  The nice thing is, the larger cogs/spider where the machining was done are the cogs that will wear out slowest, so I could potentially re-use just that piece of the cassette through several worn cassette replacements.  It was an investment that I might not have made except that I already knew that gearing was what I really wanted.
