Self-install possible for upgrade from 1 Gb/s to a 3 Gb/s plan?

[wireless]

I currently have Telus pure fibre 1 Gb/s service with NH20A. If I decide to upgrade to the 3 Gb/s service do I need to wait for installer to replace Nokia GPON ONT SFP (G-010S-A) with XGS-PON SFP+ version in NH20A, or is it possible for Telus to mail new module and I make a swap (then installer does what installer does at the connect box outside, wherever it is)?
