how to combine two ssd to work as one drive

[spicejesi]

Is it possible to make two ssd of different volume to work as one drive without formating

No drive, whether HDD or SSD, can be used until it's formatted, so you seem to misunderstand the term.
As to your central question, no, you can't make two physically separate drives work as one.
