Great news indeed, clubs are allowed to stream all games during the 2026-2027 season.
Normally UEFA publish the agenda at least 14 days prior to the season start, albiet last season they were 3 weeks late.
UEFA Regulations Article 48 of the UEFA Statutes

Friday the 17th July at 20:00pm was the cut off period for UEFA/SPFL to publish the block-dates criteria (14 days prior to the season start - which is July 31st at 20:00). If members do not comply then "no restrictions apply"

As that information has not been setout their are no block dates.
The regulations clearly state:

ARTICLE 3 TRANSMISSION-FREE PERIODS
2 The two and a half hours period (or periods) must be decided on by the
member association fourteen days, at the latest, before the beginning of
its domestic season, at which time they will enter into force and apply
for the whole season.

5 . . . . . If member associations do not comply with this time limit,
no restrictions will apply to the Transmission of football during that
season for the member association in question.

In season 2025-2026 UEFA/SPFL missed the cut off date but then went ahead with restrictions from the 23rd of August 2025.
When clubs break the rules they get punished, surely SPFL/SFA/UEFA have to abide by rules ?
