Impact of new products that are retrospectively affecting core rules. E.g.: TCOE

Hello hivemind, I don't own Tashas either physically or on Roll20, however I have noticed that there appears to have been some changes presumably from this product that have an affect on spell availability and probably other core rules (PHB) e.g. Revivify for Cleric & Paladin, now includes Artificer, Druid and Ranger. While this may be a boon for some DMs how does one prevent these options being available for players in Roll20, including Charactermancer? Any help appreciated.

With compendium sharing, you can turn on/off individual books you own, but can't manage them more granular than that. So it 's either to have Tasha's enabled or disabled, fairly sure there is no in-between.

Thanks for the reply, however as I said I don't own Tashas, however there are changes (spell avaiability by class, mentioned above) brought in by this product (I am assuming unless it is some sort of errata) that have been incorporated into the core rules within Roll20, buying it would not solve the issue and I don't want to have to buy it in order to figure out what is a TCOE modification and then tell my players "sorry no", what I want is Roll20 including the Charactermancer to only use the core books or additional compendiums I have bought.
