Yes you can implement it yourself – given how bad available cookie consent tools are, you're more likely to be compliant that way. However, consent under the GDPR must be specific.

Note that under EU cookie laws you don't need consent for cookies that are strictly necessary for the service requested by the user. E.g. using a cookie for dark mode preference, for a shopping cart, or for the consent status itself is perfectly fine without consent.
