This should not be needed, as it can be calculated automatically based on
https://github.com/zephyrproject-rtos/zephyr/blob/d53f324ca09dcafda0923a38f773b1538857f2f3/dts/arm/st/c0/stm32c0.dtsi#L150
and image size.

mcuboot/boot/zephyr/CMakeLists.txt

Line 515 in 7a9f30f

math(EXPR slot_min_sectors "${slot0_size} / ${erase_size_slot0}")

If it's not calculated properly when MAX_IMG_SECTORS_AUTO=y, the cause should be investigated, instead of patching the problem elsewhere which does not scale with the number of boards in Zephyr.
