I'm installing Python 2.7.11 using Chocolatey, which installs into
choco install python2 -y
Yes, override the install arguments -
choco install python2 -y -o -ia "'/qn /norestart ALLUSERS=1 TARGETDIR=c:\Python27'"
Alternatively you can create a Python27 folder and it will install there.
Note that is determined by reading through the chocolateyInstall.ps1 script - https://chocolatey.org/packages/python2#files
