Rescue disk 🤣 It's hard enough to find a drive much less a disk.
Next time keep your old kernel around a while, you can always boot it to fix a goof instead of messing around with rescue images.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

🤦♀️ I've never considered this, but it's the simplest solution and makes perfect sense. I'm always so diligent to keep my system clean to save a few megs.
This particular server is an old PowerEdge server I'm using to learn server stuff on and a practice home lab. Unfortunately, it won't boot from SD card, so I have a few DVD RW's in a drawer. I've read that there's a SD slot inside that you can emulate a floppy, but haven't explored it.
A Gentoo LiveUSB and some chroot would save your day!
Adding a netboot.xyz EFI boot menu entry can be useful if you do not need a live system often and do not have a USB stick when you do.
But don't you need a wired network connection for this to actually work?
I have only tried it with wired but it uses ipxe and that is supposed to work with Android USB tethering too to bridge to other kinds of network access.
I have the Debian netinst disk, but it doesn't include the dm-cache modules, so I downloaded the live DVD last night. I only get about an hour a day to work on stuff.
Aren't you supposed to add modules by putting them in some config file so they get added automatically?
Fixing your problem should also be achievable from single-user/rescue mode too, no need for a rescue disk.
