I suspect that's just because you're trying to install an old version (as I wrote sysdig used to have a kernel extension but now should use eBPF functionality provided in stock kernels). I can't easily verify (no ubuntu at hand), but presumably if you install the vendor supplied, up-to-date version (first google hit I found: https://www.linuxcapable.com/how-to-install-sysdig-on-ubuntu...) it will work without UEFI changes.
