This will do it automatically.

Configuration

Common Settings

# /boot/EFI/refind/refind.conf
scan_delay 5    # wait 5s to scan for disks (helps if ex. windows not detected)
timeout 10      # boot after 10s unless a key is pressed
resolution max  # use max possible resolution

Kernel Options

First, generate a /boot/refind_linux.conf if it doesn't exist (it applies to all kernels in the same directory).

test -f /boot/refind_linux.conf || mkrlconf

Next, adjust the boot options you'd like within the subsection you'd like

# /boot/refind_linux.conf

"Boot with standard options"  "root=PARTUUID=${SOME_PARTUUID} rw rdblacklist=nouveau nomodeset systemd.unified_cgroup_hierarchy=0 ${YOUR_KERNEL_PARAMS}"
"Boot to single-user mode"    "root=PARTUUID=${SOME_PARTUUID} rw rdblacklist=nouveau nomodeset single ${YOUR_KERNEL_PARAMS}"
"Boot with minimal options"   "ro root=UUID=${SOME_PARTUUID} ${YOUR_KERNEL_PARAMS}"
