No, the Sapphire v7.5 installer will replace all other versions of Sapphire AVX (but not versions for other host products). This prevents confusion from multiple copies of the same effects, and allows your saved projects to automatically use the new version. To use an older version of Sapphire on your machine, please uninstall the current version and install the older version.

If you intend on using an older Avid DS product that did not support AVX2, be sure to use the AVX1 version, which is indicated with an "(avx1)" appended to the category name.
