Well, it doesn't matter which one of your posts you refer to - the information regarding needing to upgrade to 10.13 first in order to upgrade to Big Sur is simply not correct.
Here are the published requirements for Big Sur from Apple. The minimum OS is 10.9 which is obviously older than 10.13.
Back up your data, check your applications for compatibility, and click on High Sierra, Mojave, Catalina, or Big Sur.

For Note:
To go past High Sierra (Mojave, Catalina, or Big Sur), you have to upgrade to High Sierra first, then proceed with the upgrade to any of those three.

Installing this One-By-One:
You have me wondering if I may be mis-comprehending(so-to-speak) the OP. I am comprehending it as though they want to know with which macOS it is compatible with. So, what I’m getting at is to install the macOS one-by-one (as they work their way up with the macOS version chain, later-and-later). And then stop once incompatibility comes about.
Is that how you are comprehending it?
No it isn’t. You’ve posted this information before even though the question was different and it is still incorrect - sorry. the point is that it is obviously compatible with anything up to and including big Sur. You are very clearly saying that one needs to upgrade to HS before proceeding higher - which is wrong.
If that were the case, then why does Apple not include that information in their release notes?
Why does Apple say that the minimum is 10.9 rather than 10.12 or 10.13?
Or why have I not had a problem going from Sierra directly to BS?
I prefer such important information to come from the source.
Our personal preferences do not come into play here. The advise offered was to look out for the user - first. After all, that is what the ASC Forums are here for.
As originally stated " In technical terms Yes it can go Sierra to Big Sur ". The caveat was to alert to ROM Updates involved.
As for " If that were the case, then why does Apple not include that information in their release notes? " we know that question can only be answered by the Source.

Thanks for the inappropriate and unnecessary lesson. That is precisely why I posted initially.
I will leave it at that as there is no need for any further interaction.
And here are the hardware requirements - yours is fine; however, check how much RAM you have; 8 GB is considered the minimum:
Do you have a link to that requirement please.
I upgraded straight from Sierra to big sur.
In technical terms Yes it can go Sierra to Big Sur but the HS Upgrade would better position the computer with updates of Boot ROM for the eventual move to Big Sur
OK
