Cannot use single endpoint using Route attribute and with AddRouteComponents

Assemblies affected
Microsoft.AspNetCore.OData 8.0.12

Describe the bug
I have a controller that has 4 actions: CRUD. I want to use OData only on Read. My controller should fit api/[controller] template.
I was not able to do that with OData. It is opening two endpoints or showing some errors

Reproduce steps
My controller:

[Route("api/[controller]")]
    public class CustomersController : ControllerBase
    {
        private static Random random = new Random();
        private static List<Customer> customers = new List<Customer>(
            Enumerable.Range(1, 3).Select(idx => new Customer
            {
                Id = idx,
                Name = $"Customer {idx}",
                Orders = new List<Order>(
                    Enumerable.Range(1, 2).Select(dx => new Order
                    {
                        Id = (idx - 1) * 2 + dx,
                        Amount = random.Next(1, 9) * 10
                    }))
            }));

        [HttpGet()]
        [EnableQuery]
        public ActionResult Get()
        {
            return Ok(customers);
        }

        [HttpPut()]
        public ActionResult Put()
        {
            return Ok();
        }

        [HttpPost()]
        public ActionResult Post()
        {
            return Ok();
        }

        [HttpDelete]
        public ActionResult Delete()
        {
            return Ok();
        }
    }

I am using AddRouteComponents("api", modelBuilder.GetEdmModel())), because my controller has api prefix

It is throwing an error:

Microsoft.AspNetCore.Routing.Matching.AmbiguousMatchException: The request matched multiple endpoints. Matches: 

WebApplication3.Controllers.CustomersController.Get (WebApplication3)

   at Microsoft.AspNetCore.Routing.EndpointRoutingMiddleware.<Invoke>g__AwaitMatch|8_1(EndpointRoutingMiddleware middleware, HttpContext httpContext, Task matchTask)
   at Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddlewareImpl.Invoke(HttpContext context)

Expected behavior
It should use endpoint without an error
