基于 custom-esbuild，通过自己写一个 esbuild plugin，设置 logOverride ，将 ignored-bare-import 的 log level 设置为 silent 解决了

esbuild plugin 的实现代码 setup-esbuild.ts

import type { Plugin, PluginBuild } from 'esbuild';

const setupEsbuild: Plugin = {
  name: 'setup-esbuild',
    setup(pluginBuild: PluginBuild) {
        pluginBuild.initialOptions.logOverride = {
            "ignored-bare-import": "silent"
        }
    },
};

export default setupEsbuild;

npm 安装 custom-esbuild

npm i @angular-builders/custom-esbuild

angular.json 中启用 custom-esbuild 与 setupEsbuild plugin

"build": {
    "builder": "@angular-builders/custom-esbuild:application",
    "options": {
        "plugins": [ "./build/esbuild/setup-esbuild.ts" ]
    }
}
