You may want to disable secure boot early anyway (from within Win10).

My usual practice is to use something like /data (or /data1../datan for multiple "extra" partitions) and then create directories in these partitions for any users that need the space; the user then has a symbolic link "data" (or whatever name you prefer) in their home directory to their directory on the extra partition. Another approach sometimes used is to mount the extra partition as /home so all users home directories are there by default, leaving the SSD entirely for system purposes, though this can be more difficult to deal with if the second drive fails (your user won't have their home directory available).  If you're prepared to play around with installing in VirtualBox (in Win10 if you wish) first you can easily simulate a 2 drive system and figure out the installation process before trying it on the hardware.
