Please supply ideas for how to install a newer version of cURL if you have one.
The same way as custombuild did it before. Customubuild is a script which was initially written by a 3rd part developer Martynas. And now it's an important part of Directadmin. There are no obligations to use software from CustomBuild at all. You might compile your own software and/or even install packages from RPM.
cURL developers offer an official method to build it from source: https://curl.se/docs/install.html
p.s. It's nice to have an auto committed git repository and track all the changes under ./custombuild/ on my server. That way I can see how the things developed and changed. There were 2,390 commits tracked on my private server for the latest 6 years. It's not a big deal to create a simple script to compile cURL.
