Downgrade facilitation to 2018 from CorelDRAW Graphics Suite 2019 For Windows

can we downgrade to 2018 version from CorelDRAW Graphics Suite 2019 For Windows

since the end user plotter is supporting the drivers for CorelDRAW 2018 version only.

if downgrade option is there, then i can buy CorelDRAW Graphics Suite 2019 this license.
