Debuginfo-install via RPM rather than dnf (or yum)?

Support
1

We build our system from AlmaLinux RPMs via rpm
(installing a list of hand-selected RPMs), rather than using yum (or dnf).
Occasionally, we override dependencies using –nodeps.

The resultant system installs, boots, and runs. However, gdb says

Missing separate debuginfos, use: yum debuginfo-install tgc-ui_core-5.5.8.4-12069.x86_64

I have read a bit about debuginfo-install, which is
/usr/bin/debuginfo-install: symbolic link to /usr/libexec/dnf-utils
/usr/libexec/dnf-utils: Python script, ASCII text executable

Is there a way to install the debuginfo gdb wants using rpm and paths to the RPMs,
rather than using yum or dnf?
