GTV dependants 5 years qualifying period for ILR

[portosru]

I am switching to GTV from Tier2 (general), which started in Feb 2020. I also was on Tier4 (student) for 5 years before Tier2. All that time my dependants were in the UK with their TIer2 dependant and Tier4 dependant visas respectively.
The question: If I apply for ILR in Feb 2023 (after 3 years on GTV fast track), would the continuous residency period for dependants include the time they spent on Tier4 visa into the 5 years required for them to qualify for ILR?
Would appreciate your response with clarifications on this situation.

I mean, can the Dependants apply for their ILR together with me after having spent 3 years with GTV and Tier2 dependant visas and combine their 2 years on the Tier4 Dependant visas for the qualifying 5 years.
The appendix says "GT 30.1. The applicant must have spent a continuous period of 5 years in the UK with permission as a dependent partner of the person (P) in GT 27.1."
Would this mean that period spent with Tier4 Dependant visa can be counted in the 5 years?

Yes. As long as their last leave was under GT visa
