A lithium-ion battery will still charge (slowly) at very low current. To avoid overcharge you must keep the voltage below 4.23V. Normally this is done by reducing charge current when it gets to 4.2V. I don't know what a 'shunt' battery charger is, but proper Li-ion charger IC's and modules are cheap and readily available.

From what I have read so far the newer cars equipped with a low voltage lithium battery will not boost from a standard 12v booster pack simply because the voltage is too low.
However, this is only partially true. The lithium-ion battery’s voltage increases as it charges, but the relationship is not linear. It can vary based on several factors, including the battery’s age and temperature. For instance, a typical lithium-ion cell might show a voltage of 3.7V at 50% charge.
The notion that lithium-ion batteries should constantly be fully recharged to 100% before use is another myth. Data shows that partial charges can be more beneficial. According to Battery University, lithium-ion batteries do not require a complete charge cycle, and partial discharges with frequent recharges are preferable.
The Cadex “boost” function halts the charge if the voltage does not rise normally. When boosting a battery, assure correct polarity. Advanced chargers and battery analyzers will not service a battery if placed in reverse polarity. A sleeping Li-ion does not reveal the voltage, and boosting must be done with awareness.
Lithium-ion batteries operate differently. They charge under a constant current and switch to a continuous voltage later in the charging cycle. The charging process reduces the current as the battery reaches its full capacity to prevent overcharging.
