Didn't help. But, I don't know if your third test equates to my third
test. What I did was prepend # to the last line in that file:

# cat initramfs-tools
#!/bin/sh -e

version="$1"
bootopt=""

command -v update-initramfs >/dev/null 2>&1 || exit 0

# passing the kernel version is required
if [ -z "${version}" ]; then
        echo >&2 "W: initramfs-tools: ${DPKG_MAINTSCRIPT_PACKAGE:-kernel package} did not pass a version number"
        exit 2
fi

# exit if kernel does not need an initramfs
if [ "$INITRD" = 'No' ]; then
        exit 0
fi

# absolute file name of kernel image may be passed as a second argument;
# create the initrd in the same directory
if [ -n "$2" ]; then
        bootdir=$(dirname "$2")
        bootopt="-b ${bootdir}"
fi

# avoid running multiple times
if [ -n "$DEB_MAINT_PARAMS" ]; then
        eval set -- "$DEB_MAINT_PARAMS"
        if [ -z "$1" ] || [ "$1" != "configure" ]; then
                exit 0
        fi
fi

# we're good - create initramfs.  update runs do_bootloader
# shellcheck disable=SC2086
#update-initramfs -c -k "${version}" ${bootopt} >&2

Thanks. That pacified the scripts. Now I can get on with finding a
kernel that supports booting with two displays connected at boot,
if there exists one packaged for Debian yet. ;)
