How to defer kernel updates until the corresponding "linux-headers" package is available?

I'm using Debian 12 Bookworm, and currently, when I run

-a

, it shows:

Linux pctxd 6.1.0-20-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.85-1 (2024-04-11) x86_64 GNU/Linux

The package linux-image-6.1.0-21-amd64 and related packages are ready to install. However, the corresponding linux-headers-6.1.0-21-amd64 package is not available. Without these headers, the Nvidia drivers can't be compiled, rendering the graphical user interface non-functional—something I learned the hard way during the last upgrade to 6.1.85-1. Running aptitude show yields:

Package: linux-image-6.1.0-21-amd64      
Version: 6.1.90-1
New: yes
State: not installed
Priority: optional
Section: kernel
Maintainer: Debian Kernel Team 
Architecture: amd64
Uncompressed Size: 408 M
Depends: kmod, linux-base (>= 4.3~), initramfs-tools (>= 0.120+deb8u2) | linux-initramfs-tool
Recommends: firmware-linux-free, apparmor
Suggests: linux-doc-6.1, debian-kernel-handbook, grub-pc | grub-efi-amd64 | extlinux
Conflicts: linux-image-6.1.0-21-amd64-unsigned
Breaks: fwupdate (< 12-7), initramfs-tools (< 0.120+deb8u2), wireless-regdb (< 2019.06.03-1~)
Replaces: linux-image-6.1.0-21-amd64-unsigned
Provides: $kernel (= 6.1.90-1)

Just now, web page Package: linux-headers-6.1.0-21-amd64 seems to describe the missing package, but clicking the “list of files” button results in a error page with the information “No such package in this suite on this architecture.” Currently, there is another Security update (regarding libglib2.0) waiting. So, the time lag between the kernel security update and the linux header files necessary for my graphic UI is a increasing risk. For future updates: Is there a way to automatically defer the kernel update until the linux-headers package is available but process the security updates of other packages?
