How to remove 'top' command's header?

Question

I have top as above, and would like to remove header.

I tried to look into its sourcecode but can't find what should be changed to remove its header, trying to modify and create a patch.

Not quite right, I need to start top that doesn't have header, in your link, the output doesn't have header. — Tuyen Pham, Sep 24 '18 at 12:59
https://github.com/mmalecki/procps/blob/master/top.c#L2101 seems to be the area — Jeff Schaller, Sep 24 '18 at 13:04
It's weird when I try to re-build package with makepkg - I use archlinux. After build, modified top.c file always restore to its original file. — Tuyen Pham, Sep 24 '18 at 13:27

Can we keep texts: PID USER ..etc but remove background only? — Tuyen Pham, Jun 22 '19 at 05:16

To remove the background only, just press Z then T and up/down until you match the background, then Enter to save and W to persist the new settings in your config file.

This solution does not remove the header as indicated by OP on my Linux system. It does indeed change the header ABOVE the header BAR that OP wants removed, but not the bar itslef as indicated by the original question. For this reason, downvoted. – number9 Jun 30 '22 at 12:59
