Thank you.
Many of the boutique sellers will do this, or you can clean install yourself. Here is one such, but many if not most offer bloatfree OS.

I used to own a Lenovo Thinkpad T510 and back then the only way I found have a "clean" installation and be able to re-install things myself was to purchase a new Windows license key.
Otherwise, the restoration discs (I don't remember if they were CD or DVDs would re-install the full Lenovo "updater" or something which would grab all initial software that I didn't need and slowed the computer. And then I had to go quite carefully if I wanted to just install the useful drivers and not automatically fetch all the reste of the "extra-softwares"... (Memories are far and imprecise).
I don't think the sellers where I live would do it without extra cost.
(I did't not find the OS options.)
Your definition of "bloatware" may be very different from mine. You may be one of those users that believes that you have to disable a bunch of services to maximize performance.
The most typical "visible" things that I consider bloatware are things are things like having a limit license of things like Norton Security or Ashampoo utilities pre-installed with the OS and forced into "restoration" material. Actually even Microsoft Office installed without request... (Also but that's something I saw on mobile but I don't if it has come to PC yet, things like Facebook app or so that can't be uninstalled)
Then stuff that constantly connect to the internet (possibly at start) and throws notifications or ads or leaks data.
I would also consider hidden extra services that don't really bring something to computer maintenance as bloatware, but I usually don't go as far as inspecting all services.
The lenovo thinkpad units are good in this respect.
Considering my past experience with Lenovo Thinkpad T510, I'm a bit surprised.... but well T510 is old.
