Is there a way to sync my fork with upstream from UI via rebase, but not a merge?
It would be a super awesome to have an option for this action

Yes, there is a way to sync your fork with upstream via rebase, but not a merge, using the GitHub UI. Here's how you can do it:

• Open your fork on GitHub and navigate to the "Pull requests" tab.
  

• Click on the "New pull request" button.
  

• On the "Comparing changes" page, set the base repository to the upstream repository that you want to sync with, and set the base branch to the branch you want to update. Set the head repository to your fork, and set the compare branch to the branch that you want to merge.
  

• GitHub will show that there is nothing to compare, so click on the "switching the base" link.
  

• On the "Choose a base" page, select the branch that you want to update, and then click the "Create pull request" button.
  

• In the "Open a pull request" page, click on the "Edit" button next to the "Merge" button.
  

• Change the merge method from "Create a merge commit" to "Rebase and merge."
  

• Click on the "Confirm rebase and merge" button to complete the process.
  

GitHub will now rebase your changes on top of the upstream changes and merge them into the base branch. This will result in a linear history, without an additional merge commit.

In the "Open a pull request" page, click on the "Edit" button next to the "Merge" button.

There's no "Merge" button, nor the "Edit" button next to it, on that page... There's only the "Create pull request" button under the input box for the PR detailed description. The button has a down arrow allowing to select "Create pull request" (checked by default) or "Create draft pull request". Looks like there's a step (or two) missing in the above details...
