Short answer NO, (EDITED there is a maybe way - see PS)
TTS-1 is a DXi not VSTi and it is "entangled" within the Windows registry unlike vast majority of VST's/VSTi's. If you uninstall either "Cakewalk" program (Music Creator or the Bandlab version) they will uninstall the TTS-1 DXi (and other shared "stuff").
If you installed Music Creator before Bandlab's Cakewalk - you WILL need to reinstall Cakewalk, because it will uninstall somethings (e.g., TTS-1, shared dll's) required by Cakewalk.
But Cakewalk by Bandlab is essentially a current up to date FREE version of Sonar Platinum a pro level DAW (albeit Cakewalk Platinum without all the extra free stuff, 3rd party programs, VSTi's, etc. like XLN Additive Drums, Dimension/Rapture Pro, etc.).
IMHO, now that it is (mostly) divorced from the "old" Cakewalk team, Sonar is worth keeping around especially since it's a FREE full featured DAW.
Good luck

EDIT add on:
PS - there are tools that will allow you to "install and register" a DX/DXi but you'd have to go find (i.e., know where they are) the TTS-1 files (usually in the "X:\...\Cakewalk\Shared DXi\TTS-1\" folder and try running "C:\Windows\System32\regsrv32.exe"

Good luck again
soap box on
That was always a problem with TwelveTone/Cakewalk company software installs that hacked me off to the point that 11 months before Gibson dropped Cakewalk/Sonar - I dropped Cakewalk/Sonar (after 25+ years) because their messy installs and lack of flexibility during installs (long story) got to be too much for me. Cakewalk installs were (and still are) messy, installs to redundant crap, and worse - installs do NOT keep track of a count of identical software/programs already installed so that shared programs, dlls, library's, etc. can be de-installed by simply decrementing install counts within registry without actually UNINSTALLING or performing other destructive procedures affecting software that is not being uninstalled.
Unfortunately this install/uninstall behavior was never cleaned up/fixed/modified by the "new" Bandlab team (probably because a lot of the same folks are involved and human laziness "why re-design/re-write tools that [sort of] work")
