Sponsorblock theoretically exists
In its current form, it would only work if each video had the ads injected at the same timestamp and with the same duration everytime, which I find unlikely.
It would have to implement some dynamic behavior. It is however in at least some countries required to visibly and clearly mark ads, so a check for that marking could possibly be implemented. But that's more of a thing I'd expect uBO to do instead of Sponsorblock.
Going by recent internet history, every anti-adblock measure will have its according anti-anti-adblock measure within at most a few weeks by now. That's the beauty of community-driven open source projects.
The L14 Gen1 I have must be an exception then. The fingerprint reader isn't compatible at all (I feel kinda taken for a ride there since it's seemingly the only Synaptics reader without Linux compatibility) and both Bluetooth and USB are very buggy. I haven't used it with Windows, so the latter two may also be down to crappy firmware. Either way I'm rather disappointed for the price tag and probably not buying Lenovo again any time soon.
