How to skip efi partition

I would like to install mabox linux on my ssd nvme internal hard disk with dual boot. While, selecting separate partition, installers ask efi partition to install boot loader. However, I dont want automatic install of boot loader. As I have separate efi (gpt) partition for refind.conf. I would like to configure manually mabox parameters on my refind.conf. No skip option for boot loader is found on installer?
