Post vids of this happening for best advice.
For some people a bit of knee cave isn’t bad because they go from a varus position to neutral so like not going excessive valgus/ knee caving.
For some people cuing, targeted warm up and hip + foot muscular activation and practicing will resolve the issue.
For some people targeted hip strengthening work may be required but I’d try cuing, activation and technique work stuff first. Could also be related to your foot stability e.g. if ur feet tend to roll inwards ur knees can follow.
You’ll have to do some self assessment and see what seems to fit ur issue
