Are there technical limitation to multiple "VPN"s?

On my PC (Windows 11) I can simultaneously use zScaler and Tailscale. They work in different ways but ultimately they build micro-tunnels for specific destination IPs (using the IPv4 CGNAT or IPv6). I noticed that my phone (Samsung Galaxy 25+, Android 13) refuses to have both living together (it becomes a network mess). My question: Does Android support two or more simultaneous "VPN"s (the naming is not clear). Or in other words: can I have two small keys at the same time in the top bar (which would indicate two VPNs working simultaneously)? I am especially interested in the core availability ("are two possible at all") more than possible conflicts (which are a problem but may be fixable through configuration like in the case of default zScaler and Tailscale configurations)
