Our sources had earlier reported that Intel's 11th Generation Rocket Lake-S Desktop CPUs will be compatible on the Z490 motherboard platform but MSI has further confirmed that even lower-tier 400-series motherboards will support Intel's next-generation processors.

The support is mentioned within documents from MSI which have been spotted by Momomo_US (via Videocardz). According to those, MSI plans to bring Rocket Lake CPU support all the way down to its H410 tier of motherboards. There's no doubt that other board manufacturers will also follow MSI and offer similar support on their own entry-level products. The document further lists down that Rocket Lake-S CPUs with 65W TDPs to be supported by entry-level motherboards. This makes sense since the entry-level boards won't be able to provide any overclocking capabilities that one gets on higher-end motherboards along with unlocked CPUs.
